Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511028, here are decompositions:

97 + 510931 = 511028
109 + 510919 = 511028
139 + 510889 = 511028
181 + 510847 = 511028
211 + 510817 = 511028
277 + 510751 = 511028
337 + 510691 = 511028
409 + 510619 = 511028

Showing the first eight; more decompositions exist.
