Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501408, here are decompositions:

7 + 501401 = 501408
41 + 501367 = 501408
67 + 501341 = 501408
109 + 501299 = 501408
137 + 501271 = 501408
151 + 501257 = 501408
179 + 501229 = 501408
191 + 501217 = 501408

Showing the first eight; more decompositions exist.
