Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523628, here are decompositions:

31 + 523597 = 523628
109 + 523519 = 523628
139 + 523489 = 523628
211 + 523417 = 523628
241 + 523387 = 523628
271 + 523357 = 523628
277 + 523351 = 523628
331 + 523297 = 523628

Showing the first eight; more decompositions exist.
