Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501390, here are decompositions:

7 + 501383 = 501390
23 + 501367 = 501390
47 + 501343 = 501390
73 + 501317 = 501390
103 + 501287 = 501390
157 + 501233 = 501390
167 + 501223 = 501390
173 + 501217 = 501390

Showing the first eight; more decompositions exist.
