Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150180, here are decompositions:

11 + 150169 = 150180
29 + 150151 = 150180
73 + 150107 = 150180
83 + 150097 = 150180
89 + 150091 = 150180
97 + 150083 = 150180
103 + 150077 = 150180
113 + 150067 = 150180

Showing the first eight; more decompositions exist.
