Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523418, here are decompositions:

31 + 523387 = 523418
61 + 523357 = 523418
67 + 523351 = 523418
157 + 523261 = 523418
199 + 523219 = 523418
211 + 523207 = 523418
241 + 523177 = 523418
397 + 523021 = 523418

Showing the first eight; more decompositions exist.
