Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30862, here are decompositions:

  • 3 + 30859 = 30862
  • 11 + 30851 = 30862
  • 23 + 30839 = 30862
  • 53 + 30809 = 30862
  • 59 + 30803 = 30862
  • 89 + 30773 = 30862
  • 149 + 30713 = 30862
  • 173 + 30689 = 30862

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30862 first appears in π at position 94,183 of the decimal expansion (the 94,183ordinal-suffix:rd 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.
