Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446054, here are decompositions:

23 + 31446031 = 31446054
43 + 31446011 = 31446054
71 + 31445983 = 31446054
97 + 31445957 = 31446054
113 + 31445941 = 31446054
137 + 31445917 = 31446054
163 + 31445891 = 31446054
191 + 31445863 = 31446054

Showing the first eight; more decompositions exist.
