Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33642, here are decompositions:

  • 5 + 33637 = 33642
  • 13 + 33629 = 33642
  • 19 + 33623 = 33642
  • 23 + 33619 = 33642
  • 29 + 33613 = 33642
  • 41 + 33601 = 33642
  • 43 + 33599 = 33642
  • 53 + 33589 = 33642

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33642 first appears in π at position 616,190 of the decimal expansion (the 616,190ordinal-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.
