Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75808, here are decompositions:

  • 11 + 75797 = 75808
  • 41 + 75767 = 75808
  • 101 + 75707 = 75808
  • 149 + 75659 = 75808
  • 167 + 75641 = 75808
  • 179 + 75629 = 75808
  • 191 + 75617 = 75808
  • 197 + 75611 = 75808

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 75808 first appears in π at position 231,650 of the decimal expansion (the 231,650ordinal-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.
