Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446012, here are decompositions:

29 + 31445983 = 31446012
53 + 31445959 = 31446012
71 + 31445941 = 31446012
83 + 31445929 = 31446012
149 + 31445863 = 31446012
151 + 31445861 = 31446012
163 + 31445849 = 31446012
179 + 31445833 = 31446012

Showing the first eight; more decompositions exist.
