Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15148, here are decompositions:

  • 11 + 15137 = 15148
  • 17 + 15131 = 15148
  • 41 + 15107 = 15148
  • 47 + 15101 = 15148
  • 71 + 15077 = 15148
  • 131 + 15017 = 15148
  • 179 + 14969 = 15148
  • 191 + 14957 = 15148

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15148 first appears in π at position 67,693 of the decimal expansion (the 67,693ordinal-suffix:rd 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.
