Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167180, here are decompositions:

3 + 167177 = 167180
7 + 167173 = 167180
31 + 167149 = 167180
61 + 167119 = 167180
67 + 167113 = 167180
73 + 167107 = 167180
103 + 167077 = 167180
109 + 167071 = 167180

Showing the first eight; more decompositions exist.
