Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510428, here are decompositions:

67 + 510361 = 510428
97 + 510331 = 510428
109 + 510319 = 510428
157 + 510271 = 510428
181 + 510247 = 510428
211 + 510217 = 510428
229 + 510199 = 510428
271 + 510157 = 510428

Showing the first eight; more decompositions exist.
