Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33644, here are decompositions:

  • 3 + 33641 = 33644
  • 7 + 33637 = 33644
  • 31 + 33613 = 33644
  • 43 + 33601 = 33644
  • 67 + 33577 = 33644
  • 97 + 33547 = 33644
  • 151 + 33493 = 33644
  • 157 + 33487 = 33644

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33644 first appears in π at position 177,007 of the decimal expansion (the 177,007ordinal-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.
