Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16156, here are decompositions:

  • 17 + 16139 = 16156
  • 29 + 16127 = 16156
  • 53 + 16103 = 16156
  • 59 + 16097 = 16156
  • 83 + 16073 = 16156
  • 89 + 16067 = 16156
  • 149 + 16007 = 16156
  • 197 + 15959 = 16156

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16156 first appears in π at position 16,077 of the decimal expansion (the 16,077ordinal-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.
