Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563728, here are decompositions:

5 + 563723 = 563728
71 + 563657 = 563728
167 + 563561 = 563728
227 + 563501 = 563728
239 + 563489 = 563728
281 + 563447 = 563728
311 + 563417 = 563728
317 + 563411 = 563728

Showing the first eight; more decompositions exist.
