Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3172, here are decompositions:

  • 3 + 3169 = 3172
  • 5 + 3167 = 3172
  • 53 + 3119 = 3172
  • 83 + 3089 = 3172
  • 89 + 3083 = 3172
  • 131 + 3041 = 3172
  • 149 + 3023 = 3172
  • 173 + 2999 = 3172

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3172 first appears in π at position 137 of the decimal expansion (the 137ordinal-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.
