Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13070, here are decompositions:

7 + 13063 = 13070
37 + 13033 = 13070
61 + 13009 = 13070
67 + 13003 = 13070
97 + 12973 = 13070
103 + 12967 = 13070
151 + 12919 = 13070
163 + 12907 = 13070

Showing the first eight; more decompositions exist.
