Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75730, here are decompositions:

  • 23 + 75707 = 75730
  • 41 + 75689 = 75730
  • 47 + 75683 = 75730
  • 71 + 75659 = 75730
  • 89 + 75641 = 75730
  • 101 + 75629 = 75730
  • 113 + 75617 = 75730
  • 173 + 75557 = 75730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 75730 first appears in π at position 103,002 of the decimal expansion (the 103,002ordinal-suffix:nd 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.
