Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513782, here are decompositions:

13 + 513769 = 513782
43 + 513739 = 513782
103 + 513679 = 513782
109 + 513673 = 513782
151 + 513631 = 513782
271 + 513511 = 513782
463 + 513319 = 513782
499 + 513283 = 513782

Showing the first eight; more decompositions exist.
