Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12856, here are decompositions:
- 3 + 12853 = 12856
- 47 + 12809 = 12856
- 113 + 12743 = 12856
- 167 + 12689 = 12856
- 197 + 12659 = 12856
- 317 + 12539 = 12856
- 353 + 12503 = 12856
- 359 + 12497 = 12856
Showing the first eight; more decompositions exist.

The digit sequence 12856 first appears in π at position 109,305 of the decimal expansion (the 109,305ordinal-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.
