Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582196, here are decompositions:

3 + 31582193 = 31582196
13 + 31582183 = 31582196
103 + 31582093 = 31582196
193 + 31582003 = 31582196
199 + 31581997 = 31582196
223 + 31581973 = 31582196
307 + 31581889 = 31582196
313 + 31581883 = 31582196

Showing the first eight; more decompositions exist.
