Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17874, here are decompositions:

  • 11 + 17863 = 17874
  • 23 + 17851 = 17874
  • 37 + 17837 = 17874
  • 47 + 17827 = 17874
  • 67 + 17807 = 17874
  • 83 + 17791 = 17874
  • 113 + 17761 = 17874
  • 127 + 17747 = 17874

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17874 first appears in π at position 70,505 of the decimal expansion (the 70,505ordinal-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.
