Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558934, here are decompositions:

7 + 31558927 = 31558934
37 + 31558897 = 31558934
103 + 31558831 = 31558934
163 + 31558771 = 31558934
193 + 31558741 = 31558934
241 + 31558693 = 31558934
271 + 31558663 = 31558934
307 + 31558627 = 31558934

Showing the first eight; more decompositions exist.
