Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40908, here are decompositions:

  • 5 + 40903 = 40908
  • 11 + 40897 = 40908
  • 29 + 40879 = 40908
  • 41 + 40867 = 40908
  • 59 + 40849 = 40908
  • 61 + 40847 = 40908
  • 67 + 40841 = 40908
  • 79 + 40829 = 40908

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40908 first appears in π at position 10,952 of the decimal expansion (the 10,952ordinal-suffix:nd 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.
