Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510220, here are decompositions:

3 + 510217 = 510220
17 + 510203 = 510220
41 + 510179 = 510220
83 + 510137 = 510220
131 + 510089 = 510220
173 + 510047 = 510220
257 + 509963 = 510220
281 + 509939 = 510220

Showing the first eight; more decompositions exist.
