Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510640, here are decompositions:

23 + 510617 = 510640
29 + 510611 = 510640
59 + 510581 = 510640
71 + 510569 = 510640
89 + 510551 = 510640
191 + 510449 = 510640
239 + 510401 = 510640
257 + 510383 = 510640

Showing the first eight; more decompositions exist.
