Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43858, here are decompositions:

  • 5 + 43853 = 43858
  • 71 + 43787 = 43858
  • 137 + 43721 = 43858
  • 167 + 43691 = 43858
  • 197 + 43661 = 43858
  • 251 + 43607 = 43858
  • 281 + 43577 = 43858
  • 317 + 43541 = 43858

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 43858 first appears in π at position 57,751 of the decimal expansion (the 57,751ordinal-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.
