Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518844, here are decompositions:

13 + 518831 = 518844
31 + 518813 = 518844
37 + 518807 = 518844
41 + 518803 = 518844
43 + 518801 = 518844
83 + 518761 = 518844
97 + 518747 = 518844
101 + 518743 = 518844

Showing the first eight; more decompositions exist.
