Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510438, here are decompositions:

37 + 510401 = 510438
59 + 510379 = 510438
107 + 510331 = 510438
127 + 510311 = 510438
139 + 510299 = 510438
151 + 510287 = 510438
167 + 510271 = 510438
191 + 510247 = 510438

Showing the first eight; more decompositions exist.
