Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39510, here are decompositions:

  • 7 + 39503 = 39510
  • 11 + 39499 = 39510
  • 59 + 39451 = 39510
  • 67 + 39443 = 39510
  • 71 + 39439 = 39510
  • 101 + 39409 = 39510
  • 113 + 39397 = 39510
  • 127 + 39383 = 39510

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39510 first appears in π at position 199,185 of the decimal expansion (the 199,185ordinal-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.
