Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501386, here are decompositions:

3 + 501383 = 501386
19 + 501367 = 501386
43 + 501343 = 501386
157 + 501229 = 501386
163 + 501223 = 501386
199 + 501187 = 501386
229 + 501157 = 501386
283 + 501103 = 501386

Showing the first eight; more decompositions exist.
