Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492390, here are decompositions:

  • 13 + 492377 = 492390
  • 71 + 492319 = 492390
  • 97 + 492293 = 492390
  • 109 + 492281 = 492390
  • 137 + 492253 = 492390
  • 139 + 492251 = 492390
  • 163 + 492227 = 492390
  • 277 + 492113 = 492390

Showing the first eight; more decompositions exist.
