Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520220, here are decompositions:

7 + 520213 = 520220
97 + 520123 = 520220
109 + 520111 = 520220
157 + 520063 = 520220
199 + 520021 = 520220
223 + 519997 = 520220
277 + 519943 = 520220
313 + 519907 = 520220

Showing the first eight; more decompositions exist.
