Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519994, here are decompositions:

5 + 519989 = 519994
23 + 519971 = 519994
47 + 519947 = 519994
71 + 519923 = 519994
113 + 519881 = 519994
131 + 519863 = 519994
191 + 519803 = 519994
197 + 519797 = 519994

Showing the first eight; more decompositions exist.
