Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13148, here are decompositions:

  • 139 + 13009 = 13148
  • 181 + 12967 = 13148
  • 229 + 12919 = 13148
  • 241 + 12907 = 13148
  • 307 + 12841 = 13148
  • 349 + 12799 = 13148
  • 367 + 12781 = 13148
  • 409 + 12739 = 13148

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13148 first appears in π at position 267,275 of the decimal expansion (the 267,275ordinal-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.
