Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147578010, here are decompositions:

  • 3 + 2147578007 = 2147578010
  • 13 + 2147577997 = 2147578010
  • 37 + 2147577973 = 2147578010
  • 79 + 2147577931 = 2147578010
  • 103 + 2147577907 = 2147578010
  • 139 + 2147577871 = 2147578010
  • 181 + 2147577829 = 2147578010
  • 223 + 2147577787 = 2147578010

Showing the first eight; more decompositions exist.
