Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13180, here are decompositions:

3 + 13177 = 13180
17 + 13163 = 13180
29 + 13151 = 13180
53 + 13127 = 13180
59 + 13121 = 13180
71 + 13109 = 13180
131 + 13049 = 13180
137 + 13043 = 13180

Showing the first eight; more decompositions exist.
