Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180882, here are decompositions:

11 + 180871 = 180882
71 + 180811 = 180882
83 + 180799 = 180882
89 + 180793 = 180882
103 + 180779 = 180882
109 + 180773 = 180882
131 + 180751 = 180882
151 + 180731 = 180882

Showing the first eight; more decompositions exist.
