Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523218, here are decompositions:

5 + 523213 = 523218
11 + 523207 = 523218
41 + 523177 = 523218
89 + 523129 = 523218
109 + 523109 = 523218
197 + 523021 = 523218
211 + 523007 = 523218
229 + 522989 = 523218

Showing the first eight; more decompositions exist.
