Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15028, here are decompositions:

  • 11 + 15017 = 15028
  • 59 + 14969 = 15028
  • 71 + 14957 = 15028
  • 89 + 14939 = 15028
  • 131 + 14897 = 15028
  • 137 + 14891 = 15028
  • 149 + 14879 = 15028
  • 197 + 14831 = 15028

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15028 first appears in π at position 37,510 of the decimal expansion (the 37,510ordinal-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.
