Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510722, here are decompositions:

13 + 510709 = 510722
31 + 510691 = 510722
103 + 510619 = 510722
109 + 510613 = 510722
139 + 510583 = 510722
193 + 510529 = 510722
241 + 510481 = 510722
271 + 510451 = 510722

Showing the first eight; more decompositions exist.
