Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523538, here are decompositions:

19 + 523519 = 523538
79 + 523459 = 523538
151 + 523387 = 523538
181 + 523357 = 523538
241 + 523297 = 523538
277 + 523261 = 523538
331 + 523207 = 523538
409 + 523129 = 523538

Showing the first eight; more decompositions exist.
