Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163278, here are decompositions:

19 + 163259 = 163278
29 + 163249 = 163278
67 + 163211 = 163278
79 + 163199 = 163278
97 + 163181 = 163278
107 + 163171 = 163278
109 + 163169 = 163278
127 + 163151 = 163278

Showing the first eight; more decompositions exist.
