Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13078, here are decompositions:

  • 29 + 13049 = 13078
  • 41 + 13037 = 13078
  • 71 + 13007 = 13078
  • 137 + 12941 = 13078
  • 167 + 12911 = 13078
  • 179 + 12899 = 13078
  • 257 + 12821 = 13078
  • 269 + 12809 = 13078

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13078 first appears in π at position 211,741 of the decimal expansion (the 211,741ordinal-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.
