Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30568, here are decompositions:

  • 11 + 30557 = 30568
  • 29 + 30539 = 30568
  • 59 + 30509 = 30568
  • 71 + 30497 = 30568
  • 101 + 30467 = 30568
  • 137 + 30431 = 30568
  • 179 + 30389 = 30568
  • 227 + 30341 = 30568

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30568 first appears in π at position 227,568 of the decimal expansion (the 227,568ordinal-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.
