Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101128, here are decompositions:

11 + 101117 = 101128
17 + 101111 = 101128
47 + 101081 = 101128
101 + 101027 = 101128
107 + 101021 = 101128
191 + 100937 = 101128
197 + 100931 = 101128
281 + 100847 = 101128

Showing the first eight; more decompositions exist.
