Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3228, here are decompositions:

  • 7 + 3221 = 3228
  • 11 + 3217 = 3228
  • 19 + 3209 = 3228
  • 37 + 3191 = 3228
  • 41 + 3187 = 3228
  • 47 + 3181 = 3228
  • 59 + 3169 = 3228
  • 61 + 3167 = 3228

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3228 first appears in π at position 20,136 of the decimal expansion (the 20,136ordinal-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.
