Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501428, here are decompositions:

19 + 501409 = 501428
61 + 501367 = 501428
157 + 501271 = 501428
199 + 501229 = 501428
211 + 501217 = 501428
241 + 501187 = 501428
271 + 501157 = 501428
307 + 501121 = 501428

Showing the first eight; more decompositions exist.
