Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77860, here are decompositions:

  • 11 + 77849 = 77860
  • 47 + 77813 = 77860
  • 59 + 77801 = 77860
  • 113 + 77747 = 77860
  • 137 + 77723 = 77860
  • 149 + 77711 = 77860
  • 173 + 77687 = 77860
  • 179 + 77681 = 77860

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77860 first appears in π at position 25,122 of the decimal expansion (the 25,122ordinal-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.
