Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78146, here are decompositions:

  • 7 + 78139 = 78146
  • 67 + 78079 = 78146
  • 97 + 78049 = 78146
  • 139 + 78007 = 78146
  • 163 + 77983 = 78146
  • 283 + 77863 = 78146
  • 307 + 77839 = 78146
  • 349 + 77797 = 78146

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78146 first appears in π at position 39,976 of the decimal expansion (the 39,976ordinal-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.
