Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178264, here are decompositions:

3 + 178261 = 178264
5 + 178259 = 178264
17 + 178247 = 178264
41 + 178223 = 178264
113 + 178151 = 178264
137 + 178127 = 178264
173 + 178091 = 178264
197 + 178067 = 178264

Showing the first eight; more decompositions exist.
