Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42150, here are decompositions:

11 + 42139 = 42150
19 + 42131 = 42150
61 + 42089 = 42150
67 + 42083 = 42150
79 + 42071 = 42150
89 + 42061 = 42150
107 + 42043 = 42150
127 + 42023 = 42150

Showing the first eight; more decompositions exist.
