Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3180, here are decompositions:

11 + 3169 = 3180
13 + 3167 = 3180
17 + 3163 = 3180
43 + 3137 = 3180
59 + 3121 = 3180
61 + 3119 = 3180
71 + 3109 = 3180
97 + 3083 = 3180

Showing the first eight; more decompositions exist.
