Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638150, here are decompositions:

  • 11 + 8638139 = 8638150
  • 29 + 8638121 = 8638150
  • 83 + 8638067 = 8638150
  • 89 + 8638061 = 8638150
  • 107 + 8638043 = 8638150
  • 197 + 8637953 = 8638150
  • 281 + 8637869 = 8638150
  • 359 + 8637791 = 8638150

Showing the first eight; more decompositions exist.
