Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520224, here are decompositions:

11 + 520213 = 520224
31 + 520193 = 520224
73 + 520151 = 520224
101 + 520123 = 520224
113 + 520111 = 520224
151 + 520073 = 520224
157 + 520067 = 520224
181 + 520043 = 520224

Showing the first eight; more decompositions exist.
