Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518904, here are decompositions:

11 + 518893 = 518904
37 + 518867 = 518904
41 + 518863 = 518904
73 + 518831 = 518904
97 + 518807 = 518904
101 + 518803 = 518904
103 + 518801 = 518904
137 + 518767 = 518904

Showing the first eight; more decompositions exist.
