Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31084, here are decompositions:

  • 3 + 31081 = 31084
  • 5 + 31079 = 31084
  • 71 + 31013 = 31084
  • 101 + 30983 = 31084
  • 107 + 30977 = 31084
  • 113 + 30971 = 31084
  • 173 + 30911 = 31084
  • 191 + 30893 = 31084

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31084 first appears in π at position 16,068 of the decimal expansion (the 16,068ordinal-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.
