Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510618, here are decompositions:

5 + 510613 = 510618
7 + 510611 = 510618
29 + 510589 = 510618
37 + 510581 = 510618
67 + 510551 = 510618
89 + 510529 = 510618
137 + 510481 = 510618
167 + 510451 = 510618

Showing the first eight; more decompositions exist.
