Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16160, here are decompositions:

  • 19 + 16141 = 16160
  • 73 + 16087 = 16160
  • 97 + 16063 = 16160
  • 103 + 16057 = 16160
  • 127 + 16033 = 16160
  • 223 + 15937 = 16160
  • 241 + 15919 = 16160
  • 271 + 15889 = 16160

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16160 first appears in π at position 89,757 of the decimal expansion (the 89,757ordinal-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.
