Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501078, here are decompositions:

  • 97 + 2147500981 = 2147501078
  • 199 + 2147500879 = 2147501078
  • 487 + 2147500591 = 2147501078
  • 571 + 2147500507 = 2147501078
  • 727 + 2147500351 = 2147501078
  • 739 + 2147500339 = 2147501078
  • 967 + 2147500111 = 2147501078
  • 997 + 2147500081 = 2147501078

Showing the first eight; more decompositions exist.
