Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37720, here are decompositions:

  • 3 + 37717 = 37720
  • 29 + 37691 = 37720
  • 71 + 37649 = 37720
  • 101 + 37619 = 37720
  • 113 + 37607 = 37720
  • 131 + 37589 = 37720
  • 149 + 37571 = 37720
  • 173 + 37547 = 37720

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 37720 first appears in π at position 25,976 of the decimal expansion (the 25,976ordinal-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.
