Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638152, here are decompositions:

  • 13 + 8638139 = 8638152
  • 31 + 8638121 = 8638152
  • 101 + 8638051 = 8638152
  • 109 + 8638043 = 8638152
  • 113 + 8638039 = 8638152
  • 179 + 8637973 = 8638152
  • 199 + 8637953 = 8638152
  • 223 + 8637929 = 8638152

Showing the first eight; more decompositions exist.
