Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518624, here are decompositions:

3 + 518621 = 518624
13 + 518611 = 518624
37 + 518587 = 518624
103 + 518521 = 518624
151 + 518473 = 518624
157 + 518467 = 518624
193 + 518431 = 518624
283 + 518341 = 518624

Showing the first eight; more decompositions exist.
