Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513956, here are decompositions:

13 + 513943 = 513956
19 + 513937 = 513956
127 + 513829 = 513956
229 + 513727 = 513956
277 + 513679 = 513956
283 + 513673 = 513956
307 + 513649 = 513956
643 + 513313 = 513956

Showing the first eight; more decompositions exist.
