Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23730, here are decompositions:

  • 11 + 23719 = 23730
  • 41 + 23689 = 23730
  • 43 + 23687 = 23730
  • 53 + 23677 = 23730
  • 59 + 23671 = 23730
  • 61 + 23669 = 23730
  • 67 + 23663 = 23730
  • 97 + 23633 = 23730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23730 first appears in π at position 35,273 of the decimal expansion (the 35,273ordinal-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.
