Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505212, here are decompositions:

11 + 505201 = 505212
31 + 505181 = 505212
53 + 505159 = 505212
73 + 505139 = 505212
83 + 505129 = 505212
89 + 505123 = 505212
101 + 505111 = 505212
139 + 505073 = 505212

Showing the first eight; more decompositions exist.
