Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517618, here are decompositions:

5 + 517613 = 517618
29 + 517589 = 517618
41 + 517577 = 517618
47 + 517571 = 517618
71 + 517547 = 517618
107 + 517511 = 517618
131 + 517487 = 517618
137 + 517481 = 517618

Showing the first eight; more decompositions exist.
