Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638600, here are decompositions:

  • 17 + 8638583 = 8638600
  • 83 + 8638517 = 8638600
  • 137 + 8638463 = 8638600
  • 149 + 8638451 = 8638600
  • 197 + 8638403 = 8638600
  • 227 + 8638373 = 8638600
  • 251 + 8638349 = 8638600
  • 263 + 8638337 = 8638600

Showing the first eight; more decompositions exist.
