Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482274, here are decompositions:

3 + 31482271 = 31482274
17 + 31482257 = 31482274
101 + 31482173 = 31482274
107 + 31482167 = 31482274
191 + 31482083 = 31482274
227 + 31482047 = 31482274
233 + 31482041 = 31482274
293 + 31481981 = 31482274

Showing the first eight; more decompositions exist.
