Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83680, here are decompositions:

  • 17 + 83663 = 83680
  • 41 + 83639 = 83680
  • 59 + 83621 = 83680
  • 71 + 83609 = 83680
  • 83 + 83597 = 83680
  • 89 + 83591 = 83680
  • 101 + 83579 = 83680
  • 257 + 83423 = 83680

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 83680 first appears in π at position 30,552 of the decimal expansion (the 30,552ordinal-suffix:nd 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.
