Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30086, here are decompositions:

  • 73 + 30013 = 30086
  • 97 + 29989 = 30086
  • 103 + 29983 = 30086
  • 127 + 29959 = 30086
  • 139 + 29947 = 30086
  • 223 + 29863 = 30086
  • 283 + 29803 = 30086
  • 457 + 29629 = 30086

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30086 first appears in π at position 104,072 of the decimal expansion (the 104,072ordinal-suffix:nd 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.
