Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13010, here are decompositions:

  • 3 + 13007 = 13010
  • 7 + 13003 = 13010
  • 31 + 12979 = 13010
  • 37 + 12973 = 13010
  • 43 + 12967 = 13010
  • 103 + 12907 = 13010
  • 157 + 12853 = 13010
  • 181 + 12829 = 13010

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13010 first appears in π at position 76,712 of the decimal expansion (the 76,712ordinal-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.
