Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510380, here are decompositions:

19 + 510361 = 510380
61 + 510319 = 510380
109 + 510271 = 510380
127 + 510253 = 510380
139 + 510241 = 510380
163 + 510217 = 510380
181 + 510199 = 510380
223 + 510157 = 510380

Showing the first eight; more decompositions exist.
