Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17854, here are decompositions:

  • 3 + 17851 = 17854
  • 17 + 17837 = 17854
  • 47 + 17807 = 17854
  • 71 + 17783 = 17854
  • 107 + 17747 = 17854
  • 173 + 17681 = 17854
  • 197 + 17657 = 17854
  • 227 + 17627 = 17854

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17854 first appears in π at position 473,031 of the decimal expansion (the 473,031ordinal-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.
