Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150660, here are decompositions:

11 + 150649 = 150660
43 + 150617 = 150660
53 + 150607 = 150660
71 + 150589 = 150660
73 + 150587 = 150660
89 + 150571 = 150660
101 + 150559 = 150660
109 + 150551 = 150660

Showing the first eight; more decompositions exist.
