Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519968, here are decompositions:

37 + 519931 = 519968
61 + 519907 = 519968
79 + 519889 = 519968
151 + 519817 = 519968
181 + 519787 = 519968
199 + 519769 = 519968
277 + 519691 = 519968
349 + 519619 = 519968

Showing the first eight; more decompositions exist.
