Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520394, here are decompositions:

13 + 520381 = 520394
31 + 520363 = 520394
37 + 520357 = 520394
97 + 520297 = 520394
103 + 520291 = 520394
181 + 520213 = 520394
271 + 520123 = 520394
283 + 520111 = 520394

Showing the first eight; more decompositions exist.
