Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30678, here are decompositions:

  • 7 + 30671 = 30678
  • 17 + 30661 = 30678
  • 29 + 30649 = 30678
  • 41 + 30637 = 30678
  • 47 + 30631 = 30678
  • 101 + 30577 = 30678
  • 139 + 30539 = 30678
  • 149 + 30529 = 30678

Showing the first eight; more decompositions exist.
