Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28662, here are decompositions:

  • 5 + 28657 = 28662
  • 13 + 28649 = 28662
  • 19 + 28643 = 28662
  • 31 + 28631 = 28662
  • 41 + 28621 = 28662
  • 43 + 28619 = 28662
  • 59 + 28603 = 28662
  • 71 + 28591 = 28662

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28662 first appears in π at position 94,126 of the decimal expansion (the 94,126ordinal-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.
