Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12150, here are decompositions:

  • 7 + 12143 = 12150
  • 31 + 12119 = 12150
  • 37 + 12113 = 12150
  • 41 + 12109 = 12150
  • 43 + 12107 = 12150
  • 53 + 12097 = 12150
  • 79 + 12071 = 12150
  • 101 + 12049 = 12150

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12150 first appears in π at position 286,732 of the decimal expansion (the 286,732ordinal-suffix:nd 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.
