Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130278, here are decompositions:

11 + 130267 = 130278
17 + 130261 = 130278
19 + 130259 = 130278
37 + 130241 = 130278
67 + 130211 = 130278
79 + 130199 = 130278
107 + 130171 = 130278
131 + 130147 = 130278

Showing the first eight; more decompositions exist.
