Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26646, here are decompositions:

  • 5 + 26641 = 26646
  • 13 + 26633 = 26646
  • 19 + 26627 = 26646
  • 73 + 26573 = 26646
  • 89 + 26557 = 26646
  • 107 + 26539 = 26646
  • 149 + 26497 = 26646
  • 157 + 26489 = 26646

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26646 first appears in π at position 29,449 of the decimal expansion (the 29,449ordinal-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.
