Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78340, here are decompositions:

  • 23 + 78317 = 78340
  • 29 + 78311 = 78340
  • 107 + 78233 = 78340
  • 137 + 78203 = 78340
  • 149 + 78191 = 78340
  • 167 + 78173 = 78340
  • 173 + 78167 = 78340
  • 239 + 78101 = 78340

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78340 first appears in π at position 30,230 of the decimal expansion (the 30,230ordinal-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.
