Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16228, here are decompositions:

  • 5 + 16223 = 16228
  • 11 + 16217 = 16228
  • 41 + 16187 = 16228
  • 89 + 16139 = 16228
  • 101 + 16127 = 16228
  • 131 + 16097 = 16228
  • 137 + 16091 = 16228
  • 167 + 16061 = 16228

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16228 first appears in π at position 8,396 of the decimal expansion (the 8,396ordinal-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.
