Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15146, here are decompositions:

  • 7 + 15139 = 15146
  • 73 + 15073 = 15146
  • 163 + 14983 = 15146
  • 199 + 14947 = 15146
  • 223 + 14923 = 15146
  • 277 + 14869 = 15146
  • 349 + 14797 = 15146
  • 367 + 14779 = 15146

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15146 first appears in π at position 257,531 of the decimal expansion (the 257,531ordinal-suffix:st 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.
