Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3178, here are decompositions:

11 + 3167 = 3178
41 + 3137 = 3178
59 + 3119 = 3178
89 + 3089 = 3178
137 + 3041 = 3178
167 + 3011 = 3178
179 + 2999 = 3178
239 + 2939 = 3178

Showing the first eight; more decompositions exist.
