Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86730, here are decompositions:

  • 11 + 86719 = 86730
  • 19 + 86711 = 86730
  • 37 + 86693 = 86730
  • 41 + 86689 = 86730
  • 53 + 86677 = 86730
  • 101 + 86629 = 86730
  • 103 + 86627 = 86730
  • 131 + 86599 = 86730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 86730 first appears in π at position 364,644 of the decimal expansion (the 364,644ordinal-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.
