Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40790, here are decompositions:

  • 3 + 40787 = 40790
  • 19 + 40771 = 40790
  • 31 + 40759 = 40790
  • 97 + 40693 = 40790
  • 151 + 40639 = 40790
  • 163 + 40627 = 40790
  • 181 + 40609 = 40790
  • 193 + 40597 = 40790

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40790 first appears in π at position 6,103 of the decimal expansion (the 6,103ordinal-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.
