Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16168, here are decompositions:

  • 29 + 16139 = 16168
  • 41 + 16127 = 16168
  • 71 + 16097 = 16168
  • 101 + 16067 = 16168
  • 107 + 16061 = 16168
  • 167 + 16001 = 16168
  • 197 + 15971 = 16168
  • 281 + 15887 = 16168

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16168 first appears in π at position 384,068 of the decimal expansion (the 384,068ordinal-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.
