Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447134, here are decompositions:

31 + 31447103 = 31447134
53 + 31447081 = 31447134
107 + 31447027 = 31447134
113 + 31447021 = 31447134
137 + 31446997 = 31447134
151 + 31446983 = 31447134
181 + 31446953 = 31447134
197 + 31446937 = 31447134

Showing the first eight; more decompositions exist.
