Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718478, here are decompositions:

17 + 8718461 = 8718478
47 + 8718431 = 8718478
59 + 8718419 = 8718478
71 + 8718407 = 8718478
101 + 8718377 = 8718478
227 + 8718251 = 8718478
257 + 8718221 = 8718478
281 + 8718197 = 8718478

Showing the first eight; more decompositions exist.
