Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10868, here are decompositions:

  • 7 + 10861 = 10868
  • 31 + 10837 = 10868
  • 37 + 10831 = 10868
  • 79 + 10789 = 10868
  • 97 + 10771 = 10868
  • 139 + 10729 = 10868
  • 157 + 10711 = 10868
  • 181 + 10687 = 10868

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10868 first appears in π at position 80,052 of the decimal expansion (the 80,052ordinal-suffix:nd 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.
