Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51150, here are decompositions:

13 + 51137 = 51150
17 + 51133 = 51150
19 + 51131 = 51150
41 + 51109 = 51150
79 + 51071 = 51150
89 + 51061 = 51150
103 + 51047 = 51150
107 + 51043 = 51150

Showing the first eight; more decompositions exist.
