Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6810, here are decompositions:

  • 7 + 6803 = 6810
  • 17 + 6793 = 6810
  • 19 + 6791 = 6810
  • 29 + 6781 = 6810
  • 31 + 6779 = 6810
  • 47 + 6763 = 6810
  • 73 + 6737 = 6810
  • 101 + 6709 = 6810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6810 first appears in π at position 12,165 of the decimal expansion (the 12,165ordinal-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.
