Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15012, here are decompositions:

  • 29 + 14983 = 15012
  • 43 + 14969 = 15012
  • 61 + 14951 = 15012
  • 73 + 14939 = 15012
  • 83 + 14929 = 15012
  • 89 + 14923 = 15012
  • 181 + 14831 = 15012
  • 191 + 14821 = 15012

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15012 first appears in π at position 436,453 of the decimal expansion (the 436,453ordinal-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.
