Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68800, here are decompositions:

  • 23 + 68777 = 68800
  • 29 + 68771 = 68800
  • 71 + 68729 = 68800
  • 89 + 68711 = 68800
  • 101 + 68699 = 68800
  • 113 + 68687 = 68800
  • 131 + 68669 = 68800
  • 167 + 68633 = 68800

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 68800 first appears in π at position 80,364 of the decimal expansion (the 80,364ordinal-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.
