Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519718, here are decompositions:

5 + 519713 = 519718
71 + 519647 = 519718
107 + 519611 = 519718
131 + 519587 = 519718
137 + 519581 = 519718
167 + 519551 = 519718
179 + 519539 = 519718
191 + 519527 = 519718

Showing the first eight; more decompositions exist.
