Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2256, here are decompositions:
- 5 + 2251 = 2256
- 13 + 2243 = 2256
- 17 + 2239 = 2256
- 19 + 2237 = 2256
- 43 + 2213 = 2256
- 53 + 2203 = 2256
- 103 + 2153 = 2256
- 113 + 2143 = 2256
Showing the first eight; more decompositions exist.

The digit sequence 2256 first appears in π at position 9,760 of the decimal expansion (the 9,760ordinal-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.
