Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478688, here are decompositions:

  • 37 + 478651 = 478688
  • 61 + 478627 = 478688
  • 109 + 478579 = 478688
  • 157 + 478531 = 478688
  • 229 + 478459 = 478688
  • 271 + 478417 = 478688
  • 277 + 478411 = 478688
  • 337 + 478351 = 478688

Showing the first eight; more decompositions exist.
