Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510540, here are decompositions:

11 + 510529 = 510540
59 + 510481 = 510540
83 + 510457 = 510540
89 + 510451 = 510540
137 + 510403 = 510540
139 + 510401 = 510540
157 + 510383 = 510540
179 + 510361 = 510540

Showing the first eight; more decompositions exist.
