Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30718, here are decompositions:

  • 5 + 30713 = 30718
  • 11 + 30707 = 30718
  • 29 + 30689 = 30718
  • 41 + 30677 = 30718
  • 47 + 30671 = 30718
  • 179 + 30539 = 30718
  • 227 + 30491 = 30718
  • 251 + 30467 = 30718

Showing the first eight; more decompositions exist.
