Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28360, here are decompositions:

  • 11 + 28349 = 28360
  • 41 + 28319 = 28360
  • 53 + 28307 = 28360
  • 71 + 28289 = 28360
  • 83 + 28277 = 28360
  • 131 + 28229 = 28360
  • 149 + 28211 = 28360
  • 179 + 28181 = 28360

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28360 first appears in π at position 74,162 of the decimal expansion (the 74,162ordinal-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.
