Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40740, here are decompositions:

  • 31 + 40709 = 40740
  • 41 + 40699 = 40740
  • 43 + 40697 = 40740
  • 47 + 40693 = 40740
  • 101 + 40639 = 40740
  • 103 + 40637 = 40740
  • 113 + 40627 = 40740
  • 131 + 40609 = 40740

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40740 first appears in π at position 168,367 of the decimal expansion (the 168,367ordinal-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.
