Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650428, here are decompositions:

  • 5 + 8650423 = 8650428
  • 19 + 8650409 = 8650428
  • 37 + 8650391 = 8650428
  • 67 + 8650361 = 8650428
  • 107 + 8650321 = 8650428
  • 109 + 8650319 = 8650428
  • 211 + 8650217 = 8650428
  • 239 + 8650189 = 8650428

Showing the first eight; more decompositions exist.
