Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519188, here are decompositions:

37 + 519151 = 519188
67 + 519121 = 519188
97 + 519091 = 519188
151 + 519037 = 519188
157 + 519031 = 519188
199 + 518989 = 519188
277 + 518911 = 519188
379 + 518809 = 519188

Showing the first eight; more decompositions exist.
