Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33216, here are decompositions:

  • 5 + 33211 = 33216
  • 13 + 33203 = 33216
  • 17 + 33199 = 33216
  • 37 + 33179 = 33216
  • 67 + 33149 = 33216
  • 97 + 33119 = 33216
  • 103 + 33113 = 33216
  • 109 + 33107 = 33216

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33216 first appears in π at position 18,300 of the decimal expansion (the 18,300ordinal-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.
