Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43784, here are decompositions:

  • 3 + 43781 = 43784
  • 7 + 43777 = 43784
  • 31 + 43753 = 43784
  • 67 + 43717 = 43784
  • 73 + 43711 = 43784
  • 151 + 43633 = 43784
  • 157 + 43627 = 43784
  • 193 + 43591 = 43784

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43784 first appears in π at position 16,041 of the decimal expansion (the 16,041ordinal-suffix:st 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.
