Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159090, here are decompositions:

11 + 159079 = 159090
17 + 159073 = 159090
31 + 159059 = 159090
67 + 159023 = 159090
73 + 159017 = 159090
97 + 158993 = 159090
109 + 158981 = 159090
131 + 158959 = 159090

Showing the first eight; more decompositions exist.
