Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147558930, here are decompositions:

  • 3 + 2147558927 = 2147558930
  • 19 + 2147558911 = 2147558930
  • 31 + 2147558899 = 2147558930
  • 79 + 2147558851 = 2147558930
  • 163 + 2147558767 = 2147558930
  • 199 + 2147558731 = 2147558930
  • 337 + 2147558593 = 2147558930
  • 409 + 2147558521 = 2147558930

Showing the first eight; more decompositions exist.
