Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30706, here are decompositions:

  • 3 + 30703 = 30706
  • 17 + 30689 = 30706
  • 29 + 30677 = 30706
  • 113 + 30593 = 30706
  • 149 + 30557 = 30706
  • 167 + 30539 = 30706
  • 197 + 30509 = 30706
  • 239 + 30467 = 30706

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30706 first appears in π at position 13,308 of the decimal expansion (the 13,308ordinal-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.
