Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40056, here are decompositions:

  • 17 + 40039 = 40056
  • 19 + 40037 = 40056
  • 43 + 40013 = 40056
  • 47 + 40009 = 40056
  • 67 + 39989 = 40056
  • 73 + 39983 = 40056
  • 103 + 39953 = 40056
  • 127 + 39929 = 40056

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40056 first appears in π at position 145,222 of the decimal expansion (the 145,222ordinal-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.
