Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498770, here are decompositions:

  • 3 + 2147498767 = 2147498770
  • 29 + 2147498741 = 2147498770
  • 41 + 2147498729 = 2147498770
  • 47 + 2147498723 = 2147498770
  • 113 + 2147498657 = 2147498770
  • 227 + 2147498543 = 2147498770
  • 251 + 2147498519 = 2147498770
  • 269 + 2147498501 = 2147498770

Showing the first eight; more decompositions exist.
