Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505142, here are decompositions:

3 + 505139 = 505142
13 + 505129 = 505142
19 + 505123 = 505142
31 + 505111 = 505142
109 + 505033 = 505142
151 + 504991 = 505142
199 + 504943 = 505142
241 + 504901 = 505142

Showing the first eight; more decompositions exist.
