Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189150, here are decompositions:

11 + 189139 = 189150
23 + 189127 = 189150
83 + 189067 = 189150
89 + 189061 = 189150
107 + 189043 = 189150
109 + 189041 = 189150
131 + 189019 = 189150
139 + 189011 = 189150

Showing the first eight; more decompositions exist.
