Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75686, here are decompositions:

  • 3 + 75683 = 75686
  • 7 + 75679 = 75686
  • 67 + 75619 = 75686
  • 103 + 75583 = 75686
  • 109 + 75577 = 75686
  • 283 + 75403 = 75686
  • 349 + 75337 = 75686
  • 379 + 75307 = 75686

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 75686 first appears in π at position 49,841 of the decimal expansion (the 49,841ordinal-suffix:st 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.
