Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510626, here are decompositions:

7 + 510619 = 510626
13 + 510613 = 510626
37 + 510589 = 510626
43 + 510583 = 510626
73 + 510553 = 510626
97 + 510529 = 510626
163 + 510463 = 510626
223 + 510403 = 510626

Showing the first eight; more decompositions exist.
