Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466178, here are decompositions:

5 + 31466173 = 31466178
41 + 31466137 = 31466178
59 + 31466119 = 31466178
71 + 31466107 = 31466178
89 + 31466089 = 31466178
127 + 31466051 = 31466178
179 + 31465999 = 31466178
199 + 31465979 = 31466178

Showing the first eight; more decompositions exist.
