Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30530, here are decompositions:

  • 13 + 30517 = 30530
  • 37 + 30493 = 30530
  • 61 + 30469 = 30530
  • 103 + 30427 = 30530
  • 127 + 30403 = 30530
  • 139 + 30391 = 30530
  • 163 + 30367 = 30530
  • 211 + 30319 = 30530

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30530 first appears in π at position 365 of the decimal expansion (the 365ordinal-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.
