Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501318, here are decompositions:

19 + 501299 = 501318
31 + 501287 = 501318
47 + 501271 = 501318
61 + 501257 = 501318
89 + 501229 = 501318
101 + 501217 = 501318
109 + 501209 = 501318
127 + 501191 = 501318

Showing the first eight; more decompositions exist.
