Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43678, here are decompositions:

  • 17 + 43661 = 43678
  • 29 + 43649 = 43678
  • 71 + 43607 = 43678
  • 101 + 43577 = 43678
  • 137 + 43541 = 43678
  • 179 + 43499 = 43678
  • 191 + 43487 = 43678
  • 197 + 43481 = 43678

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43678 first appears in π at position 348 of the decimal expansion (the 348ordinal-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.
