Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78804, here are decompositions:

  • 7 + 78797 = 78804
  • 13 + 78791 = 78804
  • 17 + 78787 = 78804
  • 23 + 78781 = 78804
  • 67 + 78737 = 78804
  • 83 + 78721 = 78804
  • 97 + 78707 = 78804
  • 107 + 78697 = 78804

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78804 first appears in π at position 102,831 of the decimal expansion (the 102,831ordinal-suffix:st 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.
