Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520512, here are decompositions:

61 + 520451 = 520512
79 + 520433 = 520512
89 + 520423 = 520512
101 + 520411 = 520512
103 + 520409 = 520512
131 + 520381 = 520512
149 + 520363 = 520512
151 + 520361 = 520512

Showing the first eight; more decompositions exist.
