Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718512, here are decompositions:

43 + 8718469 = 8718512
73 + 8718439 = 8718512
163 + 8718349 = 8718512
199 + 8718313 = 8718512
211 + 8718301 = 8718512
241 + 8718271 = 8718512
349 + 8718163 = 8718512
409 + 8718103 = 8718512

Showing the first eight; more decompositions exist.
