Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11564, here are decompositions:

  • 13 + 11551 = 11564
  • 37 + 11527 = 11564
  • 61 + 11503 = 11564
  • 67 + 11497 = 11564
  • 73 + 11491 = 11564
  • 97 + 11467 = 11564
  • 127 + 11437 = 11564
  • 181 + 11383 = 11564

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11564 first appears in π at position 307,684 of the decimal expansion (the 307,684ordinal-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.
