Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509280, here are decompositions:

17 + 509263 = 509280
41 + 509239 = 509280
53 + 509227 = 509280
59 + 509221 = 509280
131 + 509149 = 509280
157 + 509123 = 509280
179 + 509101 = 509280
193 + 509087 = 509280

Showing the first eight; more decompositions exist.
