Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639822, here are decompositions:

  • 3 + 8639819 = 8639822
  • 13 + 8639809 = 8639822
  • 19 + 8639803 = 8639822
  • 43 + 8639779 = 8639822
  • 73 + 8639749 = 8639822
  • 109 + 8639713 = 8639822
  • 223 + 8639599 = 8639822
  • 271 + 8639551 = 8639822

Showing the first eight; more decompositions exist.
