Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15170, here are decompositions:

  • 31 + 15139 = 15170
  • 79 + 15091 = 15170
  • 97 + 15073 = 15170
  • 109 + 15061 = 15170
  • 139 + 15031 = 15170
  • 157 + 15013 = 15170
  • 223 + 14947 = 15170
  • 241 + 14929 = 15170

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15170 first appears in π at position 89,563 of the decimal expansion (the 89,563ordinal-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.
