Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16000, here are decompositions:

  • 29 + 15971 = 16000
  • 41 + 15959 = 16000
  • 113 + 15887 = 16000
  • 191 + 15809 = 16000
  • 197 + 15803 = 16000
  • 227 + 15773 = 16000
  • 233 + 15767 = 16000
  • 239 + 15761 = 16000

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16000 first appears in π at position 111,467 of the decimal expansion (the 111,467ordinal-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.
