Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446066, here are decompositions:

5 + 31446061 = 31446066
13 + 31446053 = 31446066
83 + 31445983 = 31446066
89 + 31445977 = 31446066
107 + 31445959 = 31446066
109 + 31445957 = 31446066
137 + 31445929 = 31446066
149 + 31445917 = 31446066

Showing the first eight; more decompositions exist.
