Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519804, here are decompositions:

7 + 519797 = 519804
11 + 519793 = 519804
17 + 519787 = 519804
67 + 519737 = 519804
71 + 519733 = 519804
101 + 519703 = 519804
113 + 519691 = 519804
137 + 519667 = 519804

Showing the first eight; more decompositions exist.
