Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61678, here are decompositions:

  • 5 + 61673 = 61678
  • 11 + 61667 = 61678
  • 41 + 61637 = 61678
  • 47 + 61631 = 61678
  • 131 + 61547 = 61678
  • 167 + 61511 = 61678
  • 191 + 61487 = 61678
  • 269 + 61409 = 61678

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61678 first appears in π at position 56,671 of the decimal expansion (the 56,671ordinal-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.
