Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22730, here are decompositions:

  • 3 + 22727 = 22730
  • 13 + 22717 = 22730
  • 31 + 22699 = 22730
  • 61 + 22669 = 22730
  • 79 + 22651 = 22730
  • 109 + 22621 = 22730
  • 157 + 22573 = 22730
  • 163 + 22567 = 22730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22730 first appears in π at position 26,777 of the decimal expansion (the 26,777ordinal-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.
