Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33638, here are decompositions:

  • 19 + 33619 = 33638
  • 37 + 33601 = 33638
  • 61 + 33577 = 33638
  • 109 + 33529 = 33638
  • 151 + 33487 = 33638
  • 181 + 33457 = 33638
  • 211 + 33427 = 33638
  • 229 + 33409 = 33638

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33638 first appears in π at position 11,985 of the decimal expansion (the 11,985ordinal-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.
