Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519500, here are decompositions:

13 + 519487 = 519500
43 + 519457 = 519500
67 + 519433 = 519500
73 + 519427 = 519500
109 + 519391 = 519500
127 + 519373 = 519500
151 + 519349 = 519500
193 + 519307 = 519500

Showing the first eight; more decompositions exist.
