Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15100, here are decompositions:

  • 17 + 15083 = 15100
  • 23 + 15077 = 15100
  • 47 + 15053 = 15100
  • 83 + 15017 = 15100
  • 131 + 14969 = 15100
  • 149 + 14951 = 15100
  • 233 + 14867 = 15100
  • 257 + 14843 = 15100

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15100 first appears in π at position 31,430 of the decimal expansion (the 31,430ordinal-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.
