Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30516, here are decompositions:

  • 7 + 30509 = 30516
  • 19 + 30497 = 30516
  • 23 + 30493 = 30516
  • 47 + 30469 = 30516
  • 67 + 30449 = 30516
  • 89 + 30427 = 30516
  • 113 + 30403 = 30516
  • 127 + 30389 = 30516

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30516 first appears in π at position 90,601 of the decimal expansion (the 90,601ordinal-suffix:st 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.
