Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501720, here are decompositions:

13 + 501707 = 501720
17 + 501703 = 501720
19 + 501701 = 501720
29 + 501691 = 501720
61 + 501659 = 501720
83 + 501637 = 501720
97 + 501623 = 501720
103 + 501617 = 501720

Showing the first eight; more decompositions exist.
