Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33820, here are decompositions:

  • 11 + 33809 = 33820
  • 23 + 33797 = 33820
  • 29 + 33791 = 33820
  • 47 + 33773 = 33820
  • 53 + 33767 = 33820
  • 71 + 33749 = 33820
  • 107 + 33713 = 33820
  • 173 + 33647 = 33820

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33820 first appears in π at position 46,015 of the decimal expansion (the 46,015ordinal-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.
