Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78372, here are decompositions:

  • 5 + 78367 = 78372
  • 31 + 78341 = 78372
  • 61 + 78311 = 78372
  • 71 + 78301 = 78372
  • 89 + 78283 = 78372
  • 113 + 78259 = 78372
  • 131 + 78241 = 78372
  • 139 + 78233 = 78372

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78372 first appears in π at position 90,087 of the decimal expansion (the 90,087ordinal-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.
