Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38660, here are decompositions:

  • 7 + 38653 = 38660
  • 31 + 38629 = 38660
  • 67 + 38593 = 38660
  • 103 + 38557 = 38660
  • 199 + 38461 = 38660
  • 211 + 38449 = 38660
  • 229 + 38431 = 38660
  • 283 + 38377 = 38660

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38660 first appears in π at position 25,190 of the decimal expansion (the 25,190ordinal-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.
