Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80750, here are decompositions:

  • 3 + 80747 = 80750
  • 13 + 80737 = 80750
  • 37 + 80713 = 80750
  • 67 + 80683 = 80750
  • 73 + 80677 = 80750
  • 79 + 80671 = 80750
  • 139 + 80611 = 80750
  • 151 + 80599 = 80750

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80750 first appears in π at position 128,587 of the decimal expansion (the 128,587ordinal-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.
