Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1276, here are decompositions:

  • 17 + 1259 = 1276
  • 47 + 1229 = 1276
  • 53 + 1223 = 1276
  • 59 + 1217 = 1276
  • 83 + 1193 = 1276
  • 89 + 1187 = 1276
  • 113 + 1163 = 1276
  • 167 + 1109 = 1276

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1276 first appears in π at position 8,634 of the decimal expansion (the 8,634ordinal-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.
