Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9212, here are decompositions:

  • 3 + 9209 = 9212
  • 13 + 9199 = 9212
  • 31 + 9181 = 9212
  • 61 + 9151 = 9212
  • 79 + 9133 = 9212
  • 103 + 9109 = 9212
  • 109 + 9103 = 9212
  • 163 + 9049 = 9212

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9212 first appears in π at position 5,359 of the decimal expansion (the 5,359ordinal-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.
