Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7992, here are decompositions:

  • 29 + 7963 = 7992
  • 41 + 7951 = 7992
  • 43 + 7949 = 7992
  • 59 + 7933 = 7992
  • 73 + 7919 = 7992
  • 109 + 7883 = 7992
  • 113 + 7879 = 7992
  • 139 + 7853 = 7992

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7992 first appears in π at position 14,785 of the decimal expansion (the 14,785ordinal-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.
