Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78418, here are decompositions:

  • 17 + 78401 = 78418
  • 71 + 78347 = 78418
  • 101 + 78317 = 78418
  • 107 + 78311 = 78418
  • 227 + 78191 = 78418
  • 239 + 78179 = 78418
  • 251 + 78167 = 78418
  • 281 + 78137 = 78418

Showing the first eight; more decompositions exist.
