Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80966, here are decompositions:

  • 3 + 80963 = 80966
  • 13 + 80953 = 80966
  • 37 + 80929 = 80966
  • 43 + 80923 = 80966
  • 103 + 80863 = 80966
  • 157 + 80809 = 80966
  • 163 + 80803 = 80966
  • 229 + 80737 = 80966

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80966 first appears in π at position 153,712 of the decimal expansion (the 153,712ordinal-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.
