Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501388, here are decompositions:

5 + 501383 = 501388
47 + 501341 = 501388
71 + 501317 = 501388
89 + 501299 = 501388
101 + 501287 = 501388
131 + 501257 = 501388
179 + 501209 = 501388
191 + 501197 = 501388

Showing the first eight; more decompositions exist.
