Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26650, here are decompositions:

  • 3 + 26647 = 26650
  • 17 + 26633 = 26650
  • 23 + 26627 = 26650
  • 53 + 26597 = 26650
  • 59 + 26591 = 26650
  • 89 + 26561 = 26650
  • 137 + 26513 = 26650
  • 149 + 26501 = 26650

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26650 first appears in π at position 22,321 of the decimal expansion (the 22,321ordinal-suffix:st 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.
