Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6986, here are decompositions:

  • 3 + 6983 = 6986
  • 19 + 6967 = 6986
  • 37 + 6949 = 6986
  • 79 + 6907 = 6986
  • 103 + 6883 = 6986
  • 157 + 6829 = 6986
  • 163 + 6823 = 6986
  • 193 + 6793 = 6986

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6986 first appears in π at position 6,854 of the decimal expansion (the 6,854ordinal-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.
