Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13080, here are decompositions:

  • 17 + 13063 = 13080
  • 31 + 13049 = 13080
  • 37 + 13043 = 13080
  • 43 + 13037 = 13080
  • 47 + 13033 = 13080
  • 71 + 13009 = 13080
  • 73 + 13007 = 13080
  • 79 + 13001 = 13080

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13080 first appears in π at position 27,262 of the decimal expansion (the 27,262ordinal-suffix:nd 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.
