Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150138, here are decompositions:

7 + 150131 = 150138
31 + 150107 = 150138
41 + 150097 = 150138
47 + 150091 = 150138
61 + 150077 = 150138
71 + 150067 = 150138
97 + 150041 = 150138
127 + 150011 = 150138

Showing the first eight; more decompositions exist.
