Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31056, here are decompositions:

  • 5 + 31051 = 31056
  • 17 + 31039 = 31056
  • 23 + 31033 = 31056
  • 37 + 31019 = 31056
  • 43 + 31013 = 31056
  • 73 + 30983 = 31056
  • 79 + 30977 = 31056
  • 107 + 30949 = 31056

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31056 first appears in π at position 92,889 of the decimal expansion (the 92,889ordinal-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.
