Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13160, here are decompositions:

  • 13 + 13147 = 13160
  • 61 + 13099 = 13160
  • 67 + 13093 = 13160
  • 97 + 13063 = 13160
  • 127 + 13033 = 13160
  • 151 + 13009 = 13160
  • 157 + 13003 = 13160
  • 181 + 12979 = 13160

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13160 first appears in π at position 43,308 of the decimal expansion (the 43,308ordinal-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.
