Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446056, here are decompositions:

3 + 31446053 = 31446056
73 + 31445983 = 31446056
79 + 31445977 = 31446056
97 + 31445959 = 31446056
127 + 31445929 = 31446056
139 + 31445917 = 31446056
193 + 31445863 = 31446056
223 + 31445833 = 31446056

Showing the first eight; more decompositions exist.
