Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17212, here are decompositions:

  • 3 + 17209 = 17212
  • 5 + 17207 = 17212
  • 23 + 17189 = 17212
  • 29 + 17183 = 17212
  • 53 + 17159 = 17212
  • 89 + 17123 = 17212
  • 113 + 17099 = 17212
  • 179 + 17033 = 17212

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17212 first appears in π at position 205,168 of the decimal expansion (the 205,168ordinal-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.
