Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519142, here are decompositions:

11 + 519131 = 519142
23 + 519119 = 519142
53 + 519089 = 519142
59 + 519083 = 519142
131 + 519011 = 519142
311 + 518831 = 519142
383 + 518759 = 519142
401 + 518741 = 519142

Showing the first eight; more decompositions exist.
