Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12256, here are decompositions:

  • 3 + 12253 = 12256
  • 5 + 12251 = 12256
  • 17 + 12239 = 12256
  • 29 + 12227 = 12256
  • 53 + 12203 = 12256
  • 59 + 12197 = 12256
  • 107 + 12149 = 12256
  • 113 + 12143 = 12256

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12256 first appears in π at position 220,498 of the decimal expansion (the 220,498ordinal-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.
