Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13130, here are decompositions:

3 + 13127 = 13130
31 + 13099 = 13130
37 + 13093 = 13130
67 + 13063 = 13130
97 + 13033 = 13130
127 + 13003 = 13130
151 + 12979 = 13130
157 + 12973 = 13130

Showing the first eight; more decompositions exist.
