Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103180, here are decompositions:

3 + 103177 = 103180
89 + 103091 = 103180
101 + 103079 = 103180
113 + 103067 = 103180
131 + 103049 = 103180
137 + 103043 = 103180
173 + 103007 = 103180
179 + 103001 = 103180

Showing the first eight; more decompositions exist.
