Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639882, here are decompositions:

  • 19 + 8639863 = 8639882
  • 73 + 8639809 = 8639882
  • 79 + 8639803 = 8639882
  • 103 + 8639779 = 8639882
  • 109 + 8639773 = 8639882
  • 283 + 8639599 = 8639882
  • 331 + 8639551 = 8639882
  • 421 + 8639461 = 8639882

Showing the first eight; more decompositions exist.
