Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518594, here are decompositions:

7 + 518587 = 518594
61 + 518533 = 518594
73 + 518521 = 518594
127 + 518467 = 518594
163 + 518431 = 518594
283 + 518311 = 518594
457 + 518137 = 518594
463 + 518131 = 518594

Showing the first eight; more decompositions exist.
