Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523398, here are decompositions:

11 + 523387 = 523398
41 + 523357 = 523398
47 + 523351 = 523398
101 + 523297 = 523398
137 + 523261 = 523398
179 + 523219 = 523398
191 + 523207 = 523398
229 + 523169 = 523398

Showing the first eight; more decompositions exist.
