Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12568, here are decompositions:

  • 29 + 12539 = 12568
  • 41 + 12527 = 12568
  • 71 + 12497 = 12568
  • 89 + 12479 = 12568
  • 131 + 12437 = 12568
  • 167 + 12401 = 12568
  • 191 + 12377 = 12568
  • 239 + 12329 = 12568

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12568 first appears in π at position 11,007 of the decimal expansion (the 11,007ordinal-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.
