Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519488, here are decompositions:

31 + 519457 = 519488
61 + 519427 = 519488
97 + 519391 = 519488
139 + 519349 = 519488
181 + 519307 = 519488
241 + 519247 = 519488
271 + 519217 = 519488
337 + 519151 = 519488

Showing the first eight; more decompositions exist.
