Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495390, here are decompositions:

  • 13 + 495377 = 495390
  • 19 + 495371 = 495390
  • 29 + 495361 = 495390
  • 31 + 495359 = 495390
  • 43 + 495347 = 495390
  • 47 + 495343 = 495390
  • 53 + 495337 = 495390
  • 67 + 495323 = 495390

Showing the first eight; more decompositions exist.
