Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51822, here are decompositions:

5 + 51817 = 51822
19 + 51803 = 51822
53 + 51769 = 51822
73 + 51749 = 51822
101 + 51721 = 51822
103 + 51719 = 51822
109 + 51713 = 51822
131 + 51691 = 51822

Showing the first eight; more decompositions exist.
