Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522512, here are decompositions:

43 + 522469 = 522512
73 + 522439 = 522512
103 + 522409 = 522512
139 + 522373 = 522512
223 + 522289 = 522512
229 + 522283 = 522512
283 + 522229 = 522512
313 + 522199 = 522512

Showing the first eight; more decompositions exist.
