Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523888, here are decompositions:

11 + 523877 = 523888
41 + 523847 = 523888
59 + 523829 = 523888
251 + 523637 = 523888
257 + 523631 = 523888
311 + 523577 = 523888
317 + 523571 = 523888
347 + 523541 = 523888

Showing the first eight; more decompositions exist.
