Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16166, here are decompositions:

  • 79 + 16087 = 16166
  • 97 + 16069 = 16166
  • 103 + 16063 = 16166
  • 109 + 16057 = 16166
  • 193 + 15973 = 16166
  • 229 + 15937 = 16166
  • 277 + 15889 = 16166
  • 307 + 15859 = 16166

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16166 first appears in π at position 109,036 of the decimal expansion (the 109,036ordinal-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.
