Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26564, here are decompositions:

  • 3 + 26561 = 26564
  • 7 + 26557 = 26564
  • 67 + 26497 = 26564
  • 127 + 26437 = 26564
  • 157 + 26407 = 26564
  • 193 + 26371 = 26564
  • 271 + 26293 = 26564
  • 313 + 26251 = 26564

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26564 first appears in π at position 26,195 of the decimal expansion (the 26,195ordinal-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.
