Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6808, here are decompositions:

  • 5 + 6803 = 6808
  • 17 + 6791 = 6808
  • 29 + 6779 = 6808
  • 47 + 6761 = 6808
  • 71 + 6737 = 6808
  • 89 + 6719 = 6808
  • 107 + 6701 = 6808
  • 149 + 6659 = 6808

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6808 first appears in π at position 2,248 of the decimal expansion (the 2,248ordinal-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.
