Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20832, here are decompositions:

  • 23 + 20809 = 20832
  • 43 + 20789 = 20832
  • 59 + 20773 = 20832
  • 61 + 20771 = 20832
  • 73 + 20759 = 20832
  • 79 + 20753 = 20832
  • 83 + 20749 = 20832
  • 89 + 20743 = 20832

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20832 first appears in π at position 5,957 of the decimal expansion (the 5,957ordinal-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.
