Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523406, here are decompositions:

3 + 523403 = 523406
19 + 523387 = 523406
73 + 523333 = 523406
109 + 523297 = 523406
193 + 523213 = 523406
199 + 523207 = 523406
229 + 523177 = 523406
277 + 523129 = 523406

Showing the first eight; more decompositions exist.
