Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510128, here are decompositions:

7 + 510121 = 510128
61 + 510067 = 510128
67 + 510061 = 510128
79 + 510049 = 510128
97 + 510031 = 510128
139 + 509989 = 510128
181 + 509947 = 510128
331 + 509797 = 510128

Showing the first eight; more decompositions exist.
