Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30108, here are decompositions:

  • 5 + 30103 = 30108
  • 11 + 30097 = 30108
  • 17 + 30091 = 30108
  • 19 + 30089 = 30108
  • 37 + 30071 = 30108
  • 61 + 30047 = 30108
  • 79 + 30029 = 30108
  • 97 + 30011 = 30108

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30108 first appears in π at position 147,960 of the decimal expansion (the 147,960ordinal-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.
