Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459382, here are decompositions:

  • 43 + 31459339 = 31459382
  • 61 + 31459321 = 31459382
  • 181 + 31459201 = 31459382
  • 271 + 31459111 = 31459382
  • 313 + 31459069 = 31459382
  • 673 + 31458709 = 31459382
  • 739 + 31458643 = 31459382
  • 751 + 31458631 = 31459382

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31459382 first appears in π at position 643,548 of the decimal expansion (the 643,548ordinal-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.
