Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501284, here are decompositions:

13 + 501271 = 501284
61 + 501223 = 501284
67 + 501217 = 501284
97 + 501187 = 501284
127 + 501157 = 501284
151 + 501133 = 501284
163 + 501121 = 501284
181 + 501103 = 501284

Showing the first eight; more decompositions exist.
