Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26810, here are decompositions:

  • 73 + 26737 = 26810
  • 79 + 26731 = 26810
  • 97 + 26713 = 26810
  • 109 + 26701 = 26810
  • 127 + 26683 = 26810
  • 163 + 26647 = 26810
  • 271 + 26539 = 26810
  • 313 + 26497 = 26810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26810 first appears in π at position 62,485 of the decimal expansion (the 62,485ordinal-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.
