Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29178, here are decompositions:

5 + 29173 = 29178
11 + 29167 = 29178
31 + 29147 = 29178
41 + 29137 = 29178
47 + 29131 = 29178
101 + 29077 = 29178
151 + 29027 = 29178
157 + 29021 = 29178

Showing the first eight; more decompositions exist.
