Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443018, here are decompositions:

  • 5 + 2147443013 = 2147443018
  • 29 + 2147442989 = 2147443018
  • 41 + 2147442977 = 2147443018
  • 167 + 2147442851 = 2147443018
  • 191 + 2147442827 = 2147443018
  • 251 + 2147442767 = 2147443018
  • 389 + 2147442629 = 2147443018
  • 599 + 2147442419 = 2147443018

Showing the first eight; more decompositions exist.
