Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446954, here are decompositions:

5 + 31446949 = 31446954
17 + 31446937 = 31446954
37 + 31446917 = 31446954
61 + 31446893 = 31446954
83 + 31446871 = 31446954
101 + 31446853 = 31446954
107 + 31446847 = 31446954
193 + 31446761 = 31446954

Showing the first eight; more decompositions exist.
