888
888 is a composite number, even, a calendar year.
In Chinese culture 888 is 8 raised to the power of exaltation. If a single 八 (bā) already sounds like 发 (fā, "prosper"), three of them stack the blessing threefold, and the market agrees: addresses, phone numbers and licence plates carrying 888 change hands for real premiums, and the digits turn up everywhere from shop names to the price tags of "lucky" goods.
Half a world and two millennia away, the same number was read as a name. In Greek — where letters double as numerals — the letters of Ἰησοῦς ("Jesus") sum to 888. Early Christian writers, including the author of the Sibylline Oracles, made much of this: set against 666, the number of the Beast, and even above the sevenfold perfection of 777, the figure 888 was taken as "superabundant," overflowing past completeness.
It is a neat coincidence of two numeral systems built on the same idea — that a word can be a sum — arriving at the very same three eights, one culture hearing wealth in it and another hearing a name.

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 888, here are decompositions:
- 5 + 883 = 888
- 7 + 881 = 888
- 11 + 877 = 888
- 29 + 859 = 888
- 31 + 857 = 888
- 59 + 829 = 888
- 61 + 827 = 888
- 67 + 821 = 888
Showing the first eight; more decompositions exist.
