Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78238, here are decompositions:

  • 5 + 78233 = 78238
  • 47 + 78191 = 78238
  • 59 + 78179 = 78238
  • 71 + 78167 = 78238
  • 101 + 78137 = 78238
  • 137 + 78101 = 78238
  • 179 + 78059 = 78238
  • 197 + 78041 = 78238

Showing the first eight; more decompositions exist.
