Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72916, here are decompositions:

  • 5 + 72911 = 72916
  • 23 + 72893 = 72916
  • 47 + 72869 = 72916
  • 149 + 72767 = 72916
  • 197 + 72719 = 72916
  • 227 + 72689 = 72916
  • 269 + 72647 = 72916
  • 293 + 72623 = 72916

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72916 first appears in π at position 192,329 of the decimal expansion (the 192,329ordinal-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.
