Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518856, here are decompositions:

43 + 518813 = 518856
47 + 518809 = 518856
53 + 518803 = 518856
89 + 518767 = 518856
97 + 518759 = 518856
109 + 518747 = 518856
113 + 518743 = 518856
127 + 518729 = 518856

Showing the first eight; more decompositions exist.
