Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518672, here are decompositions:

61 + 518611 = 518672
139 + 518533 = 518672
151 + 518521 = 518672
163 + 518509 = 518672
199 + 518473 = 518672
241 + 518431 = 518672
283 + 518389 = 518672
331 + 518341 = 518672

Showing the first eight; more decompositions exist.
