Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17120, here are decompositions:

  • 3 + 17117 = 17120
  • 13 + 17107 = 17120
  • 43 + 17077 = 17120
  • 67 + 17053 = 17120
  • 73 + 17047 = 17120
  • 79 + 17041 = 17120
  • 109 + 17011 = 17120
  • 127 + 16993 = 17120

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17120 first appears in π at position 236,416 of the decimal expansion (the 236,416ordinal-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.
