Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505152, here are decompositions:

13 + 505139 = 505152
23 + 505129 = 505152
29 + 505123 = 505152
41 + 505111 = 505152
61 + 505091 = 505152
79 + 505073 = 505152
101 + 505051 = 505152
103 + 505049 = 505152

Showing the first eight; more decompositions exist.
