Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15316, here are decompositions:

  • 3 + 15313 = 15316
  • 17 + 15299 = 15316
  • 29 + 15287 = 15316
  • 47 + 15269 = 15316
  • 53 + 15263 = 15316
  • 83 + 15233 = 15316
  • 89 + 15227 = 15316
  • 167 + 15149 = 15316

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15316 first appears in π at position 29,138 of the decimal expansion (the 29,138ordinal-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.
