Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519688, here are decompositions:

5 + 519683 = 519688
41 + 519647 = 519688
101 + 519587 = 519688
107 + 519581 = 519688
137 + 519551 = 519688
149 + 519539 = 519688
167 + 519521 = 519688
179 + 519509 = 519688

Showing the first eight; more decompositions exist.
