Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519072, here are decompositions:

5 + 519067 = 519072
41 + 519031 = 519072
61 + 519011 = 519072
83 + 518989 = 519072
89 + 518983 = 519072
139 + 518933 = 519072
179 + 518893 = 519072
241 + 518831 = 519072

Showing the first eight; more decompositions exist.
