Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33100, here are decompositions:

  • 17 + 33083 = 33100
  • 29 + 33071 = 33100
  • 47 + 33053 = 33100
  • 71 + 33029 = 33100
  • 101 + 32999 = 33100
  • 107 + 32993 = 33100
  • 113 + 32987 = 33100
  • 131 + 32969 = 33100

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33100 first appears in π at position 16,013 of the decimal expansion (the 16,013ordinal-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.
