Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28654, here are decompositions:

  • 5 + 28649 = 28654
  • 11 + 28643 = 28654
  • 23 + 28631 = 28654
  • 47 + 28607 = 28654
  • 83 + 28571 = 28654
  • 107 + 28547 = 28654
  • 113 + 28541 = 28654
  • 137 + 28517 = 28654

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28654 first appears in π at position 9,729 of the decimal expansion (the 9,729ordinal-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.
