Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520478, here are decompositions:

31 + 520447 = 520478
67 + 520411 = 520478
97 + 520381 = 520478
109 + 520369 = 520478
139 + 520339 = 520478
181 + 520297 = 520478
199 + 520279 = 520478
349 + 520129 = 520478

Showing the first eight; more decompositions exist.
