Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15250, here are decompositions:

  • 17 + 15233 = 15250
  • 23 + 15227 = 15250
  • 89 + 15161 = 15250
  • 101 + 15149 = 15250
  • 113 + 15137 = 15250
  • 149 + 15101 = 15250
  • 167 + 15083 = 15250
  • 173 + 15077 = 15250

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15250 first appears in π at position 216,936 of the decimal expansion (the 216,936ordinal-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.
