Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562298, here are decompositions:

7 + 31562291 = 31562298
17 + 31562281 = 31562298
37 + 31562261 = 31562298
41 + 31562257 = 31562298
67 + 31562231 = 31562298
179 + 31562119 = 31562298
181 + 31562117 = 31562298
191 + 31562107 = 31562298

Showing the first eight; more decompositions exist.
