Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15310, here are decompositions:

  • 3 + 15307 = 15310
  • 11 + 15299 = 15310
  • 23 + 15287 = 15310
  • 41 + 15269 = 15310
  • 47 + 15263 = 15310
  • 83 + 15227 = 15310
  • 137 + 15173 = 15310
  • 149 + 15161 = 15310

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15310 first appears in π at position 103,928 of the decimal expansion (the 103,928ordinal-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.
