Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83900, here are decompositions:

  • 31 + 83869 = 83900
  • 43 + 83857 = 83900
  • 67 + 83833 = 83900
  • 109 + 83791 = 83900
  • 127 + 83773 = 83900
  • 139 + 83761 = 83900
  • 163 + 83737 = 83900
  • 181 + 83719 = 83900

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 83900 first appears in π at position 108,164 of the decimal expansion (the 108,164ordinal-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.
