Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26730, here are decompositions:

  • 7 + 26723 = 26730
  • 13 + 26717 = 26730
  • 17 + 26713 = 26730
  • 19 + 26711 = 26730
  • 29 + 26701 = 26730
  • 31 + 26699 = 26730
  • 37 + 26693 = 26730
  • 43 + 26687 = 26730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26730 first appears in π at position 99,207 of the decimal expansion (the 99,207ordinal-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.
