Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523188, here are decompositions:

11 + 523177 = 523188
19 + 523169 = 523188
59 + 523129 = 523188
79 + 523109 = 523188
139 + 523049 = 523188
157 + 523031 = 523188
167 + 523021 = 523188
181 + 523007 = 523188

Showing the first eight; more decompositions exist.
