Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8782, here are decompositions:

  • 3 + 8779 = 8782
  • 29 + 8753 = 8782
  • 41 + 8741 = 8782
  • 83 + 8699 = 8782
  • 89 + 8693 = 8782
  • 101 + 8681 = 8782
  • 113 + 8669 = 8782
  • 173 + 8609 = 8782

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8782 first appears in π at position 38,506 of the decimal expansion (the 38,506ordinal-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.
