Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446134, here are decompositions:

3 + 31446131 = 31446134
37 + 31446097 = 31446134
67 + 31446067 = 31446134
73 + 31446061 = 31446134
103 + 31446031 = 31446134
151 + 31445983 = 31446134
157 + 31445977 = 31446134
193 + 31445941 = 31446134

Showing the first eight; more decompositions exist.
