Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78678, here are decompositions:

  • 29 + 78649 = 78678
  • 71 + 78607 = 78678
  • 101 + 78577 = 78678
  • 107 + 78571 = 78678
  • 109 + 78569 = 78678
  • 137 + 78541 = 78678
  • 139 + 78539 = 78678
  • 167 + 78511 = 78678

Showing the first eight; more decompositions exist.
