Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519980, here are decompositions:

37 + 519943 = 519980
61 + 519919 = 519980
73 + 519907 = 519980
163 + 519817 = 519980
193 + 519787 = 519980
211 + 519769 = 519980
277 + 519703 = 519980
313 + 519667 = 519980

Showing the first eight; more decompositions exist.
