Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446966, here are decompositions:

13 + 31446953 = 31446966
17 + 31446949 = 31446966
29 + 31446937 = 31446966
73 + 31446893 = 31446966
107 + 31446859 = 31446966
113 + 31446853 = 31446966
127 + 31446839 = 31446966
197 + 31446769 = 31446966

Showing the first eight; more decompositions exist.
