Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513490, here are decompositions:

11 + 513479 = 513490
17 + 513473 = 513490
59 + 513431 = 513490
71 + 513419 = 513490
83 + 513407 = 513490
137 + 513353 = 513490
149 + 513341 = 513490
179 + 513311 = 513490

Showing the first eight; more decompositions exist.
