Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43786, here are decompositions:

  • 3 + 43783 = 43786
  • 5 + 43781 = 43786
  • 137 + 43649 = 43786
  • 173 + 43613 = 43786
  • 179 + 43607 = 43786
  • 269 + 43517 = 43786
  • 359 + 43427 = 43786
  • 383 + 43403 = 43786

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43786 first appears in π at position 16,830 of the decimal expansion (the 16,830ordinal-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.
