Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40938, here are decompositions:

  • 5 + 40933 = 40938
  • 11 + 40927 = 40938
  • 41 + 40897 = 40938
  • 59 + 40879 = 40938
  • 71 + 40867 = 40938
  • 89 + 40849 = 40938
  • 97 + 40841 = 40938
  • 109 + 40829 = 40938

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40938 first appears in π at position 9,892 of the decimal expansion (the 9,892ordinal-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.
