Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505224, here are decompositions:

11 + 505213 = 505224
23 + 505201 = 505224
37 + 505187 = 505224
43 + 505181 = 505224
67 + 505157 = 505224
101 + 505123 = 505224
107 + 505117 = 505224
113 + 505111 = 505224

Showing the first eight; more decompositions exist.
