Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523386, here are decompositions:

29 + 523357 = 523386
37 + 523349 = 523386
53 + 523333 = 523386
79 + 523307 = 523386
89 + 523297 = 523386
167 + 523219 = 523386
173 + 523213 = 523386
179 + 523207 = 523386

Showing the first eight; more decompositions exist.
