Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512480, here are decompositions:

13 + 512467 = 512480
37 + 512443 = 512480
61 + 512419 = 512480
127 + 512353 = 512480
193 + 512287 = 512480
211 + 512269 = 512480
229 + 512251 = 512480
313 + 512167 = 512480

Showing the first eight; more decompositions exist.
