Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38860, here are decompositions:

  • 113 + 38747 = 38860
  • 131 + 38729 = 38860
  • 137 + 38723 = 38860
  • 149 + 38711 = 38860
  • 167 + 38693 = 38860
  • 191 + 38669 = 38860
  • 251 + 38609 = 38860
  • 257 + 38603 = 38860

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38860 first appears in π at position 34,623 of the decimal expansion (the 34,623ordinal-suffix:rd 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.
