Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513630, here are decompositions:

37 + 513593 = 513630
97 + 513533 = 513630
101 + 513529 = 513630
149 + 513481 = 513630
151 + 513479 = 513630
157 + 513473 = 513630
191 + 513439 = 513630
199 + 513431 = 513630

Showing the first eight; more decompositions exist.
