Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510628, here are decompositions:

11 + 510617 = 510628
17 + 510611 = 510628
47 + 510581 = 510628
59 + 510569 = 510628
179 + 510449 = 510628
227 + 510401 = 510628
317 + 510311 = 510628
401 + 510227 = 510628

Showing the first eight; more decompositions exist.
