Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518682, here are decompositions:

61 + 518621 = 518682
71 + 518611 = 518682
103 + 518579 = 518682
139 + 518543 = 518682
149 + 518533 = 518682
173 + 518509 = 518682
211 + 518471 = 518682
251 + 518431 = 518682

Showing the first eight; more decompositions exist.
