Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501660, here are decompositions:

23 + 501637 = 501660
37 + 501623 = 501660
43 + 501617 = 501660
59 + 501601 = 501660
67 + 501593 = 501660
83 + 501577 = 501660
97 + 501563 = 501660
149 + 501511 = 501660

Showing the first eight; more decompositions exist.
