Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78860, here are decompositions:

  • 3 + 78857 = 78860
  • 7 + 78853 = 78860
  • 37 + 78823 = 78860
  • 73 + 78787 = 78860
  • 79 + 78781 = 78860
  • 139 + 78721 = 78860
  • 163 + 78697 = 78860
  • 211 + 78649 = 78860

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78860 first appears in π at position 30,019 of the decimal expansion (the 30,019ordinal-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.
