Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500628, here are decompositions:

41 + 500587 = 500628
61 + 500567 = 500628
101 + 500527 = 500628
109 + 500519 = 500628
127 + 500501 = 500628
157 + 500471 = 500628
197 + 500431 = 500628
211 + 500417 = 500628

Showing the first eight; more decompositions exist.
