Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4808, here are decompositions:
- 7 + 4801 = 4808
- 19 + 4789 = 4808
- 79 + 4729 = 4808
- 151 + 4657 = 4808
- 157 + 4651 = 4808
- 211 + 4597 = 4808
- 241 + 4567 = 4808
- 367 + 4441 = 4808
Showing the first eight; more decompositions exist.

The digit sequence 4808 first appears in π at position 104 of the decimal expansion (the 104ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
