Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43800, here are decompositions:

  • 7 + 43793 = 43800
  • 11 + 43789 = 43800
  • 13 + 43787 = 43800
  • 17 + 43783 = 43800
  • 19 + 43781 = 43800
  • 23 + 43777 = 43800
  • 41 + 43759 = 43800
  • 47 + 43753 = 43800

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43800 first appears in π at position 15,453 of the decimal expansion (the 15,453ordinal-suffix:rd 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.
