Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510440, here are decompositions:

37 + 510403 = 510440
61 + 510379 = 510440
79 + 510361 = 510440
109 + 510331 = 510440
193 + 510247 = 510440
199 + 510241 = 510440
223 + 510217 = 510440
241 + 510199 = 510440

Showing the first eight; more decompositions exist.
