Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404628, here are decompositions:

  • 7 + 2147404621 = 2147404628
  • 139 + 2147404489 = 2147404628
  • 181 + 2147404447 = 2147404628
  • 199 + 2147404429 = 2147404628
  • 487 + 2147404141 = 2147404628
  • 739 + 2147403889 = 2147404628
  • 769 + 2147403859 = 2147404628
  • 1171 + 2147403457 = 2147404628

Showing the first eight; more decompositions exist.
