Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150912, here are decompositions:

5 + 150907 = 150912
11 + 150901 = 150912
19 + 150893 = 150912
23 + 150889 = 150912
29 + 150883 = 150912
31 + 150881 = 150912
43 + 150869 = 150912
79 + 150833 = 150912

Showing the first eight; more decompositions exist.
