Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505154, here are decompositions:

31 + 505123 = 505154
37 + 505117 = 505154
43 + 505111 = 505154
103 + 505051 = 505154
127 + 505027 = 505154
163 + 504991 = 505154
211 + 504943 = 505154
277 + 504877 = 505154

Showing the first eight; more decompositions exist.
