Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520126, here are decompositions:

3 + 520123 = 520126
23 + 520103 = 520126
53 + 520073 = 520126
59 + 520067 = 520126
83 + 520043 = 520126
107 + 520019 = 520126
137 + 519989 = 520126
179 + 519947 = 520126

Showing the first eight; more decompositions exist.
