Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12040, here are decompositions:

  • 3 + 12037 = 12040
  • 29 + 12011 = 12040
  • 53 + 11987 = 12040
  • 59 + 11981 = 12040
  • 71 + 11969 = 12040
  • 101 + 11939 = 12040
  • 107 + 11933 = 12040
  • 113 + 11927 = 12040

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12040 first appears in π at position 39,574 of the decimal expansion (the 39,574ordinal-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.
