Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32800, here are decompositions:

  • 3 + 32797 = 32800
  • 11 + 32789 = 32800
  • 17 + 32783 = 32800
  • 29 + 32771 = 32800
  • 83 + 32717 = 32800
  • 107 + 32693 = 32800
  • 113 + 32687 = 32800
  • 167 + 32633 = 32800

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 32800 first appears in π at position 48,606 of the decimal expansion (the 48,606ordinal-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.
