Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28676, here are decompositions:

  • 7 + 28669 = 28676
  • 13 + 28663 = 28676
  • 19 + 28657 = 28676
  • 73 + 28603 = 28676
  • 79 + 28597 = 28676
  • 97 + 28579 = 28676
  • 103 + 28573 = 28676
  • 127 + 28549 = 28676

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28676 first appears in π at position 20,595 of the decimal expansion (the 20,595ordinal-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.
