Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31296, here are decompositions:

  • 19 + 31277 = 31296
  • 29 + 31267 = 31296
  • 37 + 31259 = 31296
  • 43 + 31253 = 31296
  • 47 + 31249 = 31296
  • 59 + 31237 = 31296
  • 73 + 31223 = 31296
  • 103 + 31193 = 31296

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31296 first appears in π at position 103,847 of the decimal expansion (the 103,847ordinal-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.
