Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510648, here are decompositions:

29 + 510619 = 510648
31 + 510617 = 510648
37 + 510611 = 510648
59 + 510589 = 510648
67 + 510581 = 510648
79 + 510569 = 510648
97 + 510551 = 510648
167 + 510481 = 510648

Showing the first eight; more decompositions exist.
