Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43866, here are decompositions:

  • 13 + 43853 = 43866
  • 73 + 43793 = 43866
  • 79 + 43787 = 43866
  • 83 + 43783 = 43866
  • 89 + 43777 = 43866
  • 107 + 43759 = 43866
  • 113 + 43753 = 43866
  • 149 + 43717 = 43866

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43866 first appears in π at position 406,455 of the decimal expansion (the 406,455ordinal-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.
