Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28746, here are decompositions:

  • 17 + 28729 = 28746
  • 23 + 28723 = 28746
  • 43 + 28703 = 28746
  • 59 + 28687 = 28746
  • 83 + 28663 = 28746
  • 89 + 28657 = 28746
  • 97 + 28649 = 28746
  • 103 + 28643 = 28746

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28746 first appears in π at position 1,948 of the decimal expansion (the 1,948ordinal-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.
