Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150666, here are decompositions:

7 + 150659 = 150666
17 + 150649 = 150666
59 + 150607 = 150666
79 + 150587 = 150666
83 + 150583 = 150666
107 + 150559 = 150666
149 + 150517 = 150666
163 + 150503 = 150666

Showing the first eight; more decompositions exist.
