Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446960, here are decompositions:

7 + 31446953 = 31446960
11 + 31446949 = 31446960
23 + 31446937 = 31446960
43 + 31446917 = 31446960
67 + 31446893 = 31446960
89 + 31446871 = 31446960
101 + 31446859 = 31446960
107 + 31446853 = 31446960

Showing the first eight; more decompositions exist.
