Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51162, here are decompositions:

5 + 51157 = 51162
11 + 51151 = 51162
29 + 51133 = 51162
31 + 51131 = 51162
53 + 51109 = 51162
101 + 51061 = 51162
103 + 51059 = 51162
131 + 51031 = 51162

Showing the first eight; more decompositions exist.
