Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150918, here are decompositions:

11 + 150907 = 150918
17 + 150901 = 150918
29 + 150889 = 150918
37 + 150881 = 150918
71 + 150847 = 150918
127 + 150791 = 150918
139 + 150779 = 150918
149 + 150769 = 150918

Showing the first eight; more decompositions exist.
