Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520140, here are decompositions:

11 + 520129 = 520140
17 + 520123 = 520140
29 + 520111 = 520140
37 + 520103 = 520140
67 + 520073 = 520140
73 + 520067 = 520140
97 + 520043 = 520140
109 + 520031 = 520140

Showing the first eight; more decompositions exist.
