Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505198, here are decompositions:

11 + 505187 = 505198
17 + 505181 = 505198
41 + 505157 = 505198
59 + 505139 = 505198
101 + 505097 = 505198
107 + 505091 = 505198
131 + 505067 = 505198
137 + 505061 = 505198

Showing the first eight; more decompositions exist.
