Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30874, here are decompositions:

  • 3 + 30871 = 30874
  • 5 + 30869 = 30874
  • 23 + 30851 = 30874
  • 71 + 30803 = 30874
  • 101 + 30773 = 30874
  • 167 + 30707 = 30874
  • 197 + 30677 = 30874
  • 281 + 30593 = 30874

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30874 first appears in π at position 55,508 of the decimal expansion (the 55,508ordinal-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.
