Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446042, here are decompositions:

11 + 31446031 = 31446042
31 + 31446011 = 31446042
59 + 31445983 = 31446042
83 + 31445959 = 31446042
101 + 31445941 = 31446042
113 + 31445929 = 31446042
151 + 31445891 = 31446042
179 + 31445863 = 31446042

Showing the first eight; more decompositions exist.
