Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510942, here are decompositions:

11 + 510931 = 510942
23 + 510919 = 510942
53 + 510889 = 510942
139 + 510803 = 510942
149 + 510793 = 510942
191 + 510751 = 510942
233 + 510709 = 510942
251 + 510691 = 510942

Showing the first eight; more decompositions exist.
