Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729222, here are decompositions:

  • 3 + 8729219 = 8729222
  • 31 + 8729191 = 8729222
  • 43 + 8729179 = 8729222
  • 163 + 8729059 = 8729222
  • 373 + 8728849 = 8729222
  • 613 + 8728609 = 8729222
  • 631 + 8728591 = 8729222
  • 643 + 8728579 = 8729222

Showing the first eight; more decompositions exist.
