Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482284, here are decompositions:

3 + 31482281 = 31482284
7 + 31482277 = 31482284
13 + 31482271 = 31482284
37 + 31482247 = 31482284
181 + 31482103 = 31482284
241 + 31482043 = 31482284
271 + 31482013 = 31482284
373 + 31481911 = 31482284

Showing the first eight; more decompositions exist.
