Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501642, here are decompositions:

5 + 501637 = 501642
19 + 501623 = 501642
41 + 501601 = 501642
79 + 501563 = 501642
131 + 501511 = 501642
139 + 501503 = 501642
149 + 501493 = 501642
179 + 501463 = 501642

Showing the first eight; more decompositions exist.
