Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180132, here are decompositions:

59 + 180073 = 180132
61 + 180071 = 180132
79 + 180053 = 180132
89 + 180043 = 180132
109 + 180023 = 180132
131 + 180001 = 180132
151 + 179981 = 180132
163 + 179969 = 180132

Showing the first eight; more decompositions exist.
