Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31266, here are decompositions:

  • 7 + 31259 = 31266
  • 13 + 31253 = 31266
  • 17 + 31249 = 31266
  • 19 + 31247 = 31266
  • 29 + 31237 = 31266
  • 43 + 31223 = 31266
  • 47 + 31219 = 31266
  • 73 + 31193 = 31266

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31266 first appears in π at position 282,274 of the decimal expansion (the 282,274ordinal-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.
