Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522518, here are decompositions:

  • 79 + 522439 = 522518
  • 109 + 522409 = 522518
  • 127 + 522391 = 522518
  • 181 + 522337 = 522518
  • 229 + 522289 = 522518
  • 307 + 522211 = 522518
  • 439 + 522079 = 522518
  • 457 + 522061 = 522518

Showing the first eight; more decompositions exist.
