Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78422, here are decompositions:

  • 139 + 78283 = 78422
  • 163 + 78259 = 78422
  • 181 + 78241 = 78422
  • 193 + 78229 = 78422
  • 229 + 78193 = 78422
  • 283 + 78139 = 78422
  • 373 + 78049 = 78422
  • 439 + 77983 = 78422

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78422 first appears in π at position 155,767 of the decimal expansion (the 155,767ordinal-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.
