Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519940, here are decompositions:

17 + 519923 = 519940
23 + 519917 = 519940
59 + 519881 = 519940
137 + 519803 = 519940
227 + 519713 = 519940
257 + 519683 = 519940
293 + 519647 = 519940
353 + 519587 = 519940

Showing the first eight; more decompositions exist.
