Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513382, here are decompositions:

11 + 513371 = 513382
29 + 513353 = 513382
41 + 513341 = 513382
71 + 513311 = 513382
113 + 513269 = 513382
179 + 513203 = 513382
251 + 513131 = 513382
281 + 513101 = 513382

Showing the first eight; more decompositions exist.
