Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518894, here are decompositions:

31 + 518863 = 518894
127 + 518767 = 518894
151 + 518743 = 518894
157 + 518737 = 518894
283 + 518611 = 518894
307 + 518587 = 518894
373 + 518521 = 518894
421 + 518473 = 518894

Showing the first eight; more decompositions exist.
