Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42874, here are decompositions:

  • 11 + 42863 = 42874
  • 53 + 42821 = 42874
  • 101 + 42773 = 42874
  • 107 + 42767 = 42874
  • 131 + 42743 = 42874
  • 137 + 42737 = 42874
  • 173 + 42701 = 42874
  • 191 + 42683 = 42874

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42874 first appears in π at position 182,985 of the decimal expansion (the 182,985ordinal-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.
