Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130148, here are decompositions:

61 + 130087 = 130148
79 + 130069 = 130148
97 + 130051 = 130148
127 + 130021 = 130148
181 + 129967 = 130148
211 + 129937 = 130148
229 + 129919 = 130148
307 + 129841 = 130148

Showing the first eight; more decompositions exist.
