Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30910, here are decompositions:

  • 17 + 30893 = 30910
  • 29 + 30881 = 30910
  • 41 + 30869 = 30910
  • 59 + 30851 = 30910
  • 71 + 30839 = 30910
  • 101 + 30809 = 30910
  • 107 + 30803 = 30910
  • 137 + 30773 = 30910

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30910 first appears in π at position 25,968 of the decimal expansion (the 25,968ordinal-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.
