Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6880, here are decompositions:

  • 11 + 6869 = 6880
  • 17 + 6863 = 6880
  • 23 + 6857 = 6880
  • 47 + 6833 = 6880
  • 53 + 6827 = 6880
  • 89 + 6791 = 6880
  • 101 + 6779 = 6880
  • 179 + 6701 = 6880

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6880 first appears in π at position 12,443 of the decimal expansion (the 12,443ordinal-suffix:rd 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.
