Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520148, here are decompositions:

19 + 520129 = 520148
37 + 520111 = 520148
127 + 520021 = 520148
151 + 519997 = 520148
229 + 519919 = 520148
241 + 519907 = 520148
331 + 519817 = 520148
379 + 519769 = 520148

Showing the first eight; more decompositions exist.
