Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13050, here are decompositions:

  • 7 + 13043 = 13050
  • 13 + 13037 = 13050
  • 17 + 13033 = 13050
  • 41 + 13009 = 13050
  • 43 + 13007 = 13050
  • 47 + 13003 = 13050
  • 67 + 12983 = 13050
  • 71 + 12979 = 13050

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13050 first appears in π at position 13,237 of the decimal expansion (the 13,237ordinal-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.
