Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523916, here are decompositions:

13 + 523903 = 523916
139 + 523777 = 523916
157 + 523759 = 523916
199 + 523717 = 523916
277 + 523639 = 523916
313 + 523603 = 523916
373 + 523543 = 523916
397 + 523519 = 523916

Showing the first eight; more decompositions exist.
