Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505130, here are decompositions:

7 + 505123 = 505130
13 + 505117 = 505130
19 + 505111 = 505130
79 + 505051 = 505130
97 + 505033 = 505130
103 + 505027 = 505130
139 + 504991 = 505130
163 + 504967 = 505130

Showing the first eight; more decompositions exist.
