Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569362, here are decompositions:

3 + 31569359 = 31569362
43 + 31569319 = 31569362
61 + 31569301 = 31569362
103 + 31569259 = 31569362
193 + 31569169 = 31569362
211 + 31569151 = 31569362
241 + 31569121 = 31569362
271 + 31569091 = 31569362

Showing the first eight; more decompositions exist.
