Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26586, here are decompositions:

  • 13 + 26573 = 26586
  • 29 + 26557 = 26586
  • 47 + 26539 = 26586
  • 73 + 26513 = 26586
  • 89 + 26497 = 26586
  • 97 + 26489 = 26586
  • 107 + 26479 = 26586
  • 127 + 26459 = 26586

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26586 first appears in π at position 2,713 of the decimal expansion (the 2,713ordinal-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.
