Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80450, here are decompositions:

  • 3 + 80447 = 80450
  • 43 + 80407 = 80450
  • 103 + 80347 = 80450
  • 109 + 80341 = 80450
  • 163 + 80287 = 80450
  • 199 + 80251 = 80450
  • 211 + 80239 = 80450
  • 229 + 80221 = 80450

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80450 first appears in π at position 156,220 of the decimal expansion (the 156,220ordinal-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.
