Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16280, here are decompositions:

  • 7 + 16273 = 16280
  • 13 + 16267 = 16280
  • 31 + 16249 = 16280
  • 97 + 16183 = 16280
  • 139 + 16141 = 16280
  • 193 + 16087 = 16280
  • 211 + 16069 = 16280
  • 223 + 16057 = 16280

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16280 first appears in π at position 121,369 of the decimal expansion (the 121,369ordinal-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.
