Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1828, here are decompositions:
- 5 + 1823 = 1828
- 17 + 1811 = 1828
- 41 + 1787 = 1828
- 107 + 1721 = 1828
- 131 + 1697 = 1828
- 191 + 1637 = 1828
- 227 + 1601 = 1828
- 257 + 1571 = 1828
Showing the first eight; more decompositions exist.

The digit sequence 1828 first appears in π at position 12,090 of the decimal expansion (the 12,090ordinal-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.
