Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501238, here are decompositions:

5 + 501233 = 501238
29 + 501209 = 501238
41 + 501197 = 501238
47 + 501191 = 501238
107 + 501131 = 501238
149 + 501089 = 501238
281 + 500957 = 501238
317 + 500921 = 501238

Showing the first eight; more decompositions exist.
