Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510642, here are decompositions:

23 + 510619 = 510642
29 + 510613 = 510642
31 + 510611 = 510642
53 + 510589 = 510642
59 + 510583 = 510642
61 + 510581 = 510642
73 + 510569 = 510642
89 + 510553 = 510642

Showing the first eight; more decompositions exist.
