Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57256, here are decompositions:
- 5 + 57251 = 57256
- 53 + 57203 = 57256
- 83 + 57173 = 57256
- 107 + 57149 = 57256
- 113 + 57143 = 57256
- 137 + 57119 = 57256
- 149 + 57107 = 57256
- 167 + 57089 = 57256
Showing the first eight; more decompositions exist.

The digit sequence 57256 first appears in π at position 147,828 of the decimal expansion (the 147,828ordinal-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.
