Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446132, here are decompositions:

31 + 31446101 = 31446132
71 + 31446061 = 31446132
79 + 31446053 = 31446132
101 + 31446031 = 31446132
149 + 31445983 = 31446132
173 + 31445959 = 31446132
191 + 31445941 = 31446132
241 + 31445891 = 31446132

Showing the first eight; more decompositions exist.
