Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501730, here are decompositions:

11 + 501719 = 501730
23 + 501707 = 501730
29 + 501701 = 501730
71 + 501659 = 501730
107 + 501623 = 501730
113 + 501617 = 501730
137 + 501593 = 501730
167 + 501563 = 501730

Showing the first eight; more decompositions exist.
