Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505250, here are decompositions:

13 + 505237 = 505250
19 + 505231 = 505250
37 + 505213 = 505250
127 + 505123 = 505250
139 + 505111 = 505250
199 + 505051 = 505250
223 + 505027 = 505250
283 + 504967 = 505250

Showing the first eight; more decompositions exist.
