Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30958, here are decompositions:

  • 17 + 30941 = 30958
  • 47 + 30911 = 30958
  • 89 + 30869 = 30958
  • 107 + 30851 = 30958
  • 149 + 30809 = 30958
  • 251 + 30707 = 30958
  • 269 + 30689 = 30958
  • 281 + 30677 = 30958

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30958 first appears in π at position 26,299 of the decimal expansion (the 26,299ordinal-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.
