Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16212, here are decompositions:

  • 19 + 16193 = 16212
  • 23 + 16189 = 16212
  • 29 + 16183 = 16212
  • 71 + 16141 = 16212
  • 73 + 16139 = 16212
  • 101 + 16111 = 16212
  • 109 + 16103 = 16212
  • 139 + 16073 = 16212

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16212 first appears in π at position 217,164 of the decimal expansion (the 217,164ordinal-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.
