Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519822, here are decompositions:

5 + 519817 = 519822
19 + 519803 = 519822
29 + 519793 = 519822
53 + 519769 = 519822
89 + 519733 = 519822
109 + 519713 = 519822
131 + 519691 = 519822
139 + 519683 = 519822

Showing the first eight; more decompositions exist.
