Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26818, here are decompositions:

  • 5 + 26813 = 26818
  • 17 + 26801 = 26818
  • 41 + 26777 = 26818
  • 59 + 26759 = 26818
  • 89 + 26729 = 26818
  • 101 + 26717 = 26818
  • 107 + 26711 = 26818
  • 131 + 26687 = 26818

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26818 first appears in π at position 125,663 of the decimal expansion (the 125,663ordinal-suffix:rd 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.
