Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518924, here are decompositions:

13 + 518911 = 518924
31 + 518893 = 518924
61 + 518863 = 518924
157 + 518767 = 518924
163 + 518761 = 518924
181 + 518743 = 518924
313 + 518611 = 518924
337 + 518587 = 518924

Showing the first eight; more decompositions exist.
