Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16320, here are decompositions:

  • 19 + 16301 = 16320
  • 47 + 16273 = 16320
  • 53 + 16267 = 16320
  • 67 + 16253 = 16320
  • 71 + 16249 = 16320
  • 89 + 16231 = 16320
  • 97 + 16223 = 16320
  • 103 + 16217 = 16320

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16320 first appears in π at position 9,192 of the decimal expansion (the 9,192ordinal-suffix:nd 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.
