Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513612, here are decompositions:

19 + 513593 = 513612
79 + 513533 = 513612
83 + 513529 = 513612
101 + 513511 = 513612
103 + 513509 = 513612
131 + 513481 = 513612
139 + 513473 = 513612
173 + 513439 = 513612

Showing the first eight; more decompositions exist.
