Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513316, here are decompositions:

3 + 513313 = 513316
5 + 513311 = 513316
47 + 513269 = 513316
59 + 513257 = 513316
113 + 513203 = 513316
149 + 513167 = 513316
179 + 513137 = 513316
233 + 513083 = 513316

Showing the first eight; more decompositions exist.
