Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75690, here are decompositions:

  • 7 + 75683 = 75690
  • 11 + 75679 = 75690
  • 31 + 75659 = 75690
  • 37 + 75653 = 75690
  • 61 + 75629 = 75690
  • 71 + 75619 = 75690
  • 73 + 75617 = 75690
  • 79 + 75611 = 75690

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 75690 first appears in π at position 65,928 of the decimal expansion (the 65,928ordinal-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.
