Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482470, here are decompositions:

31 + 31482439 = 31482470
43 + 31482427 = 31482470
127 + 31482343 = 31482470
163 + 31482307 = 31482470
193 + 31482277 = 31482470
199 + 31482271 = 31482470
223 + 31482247 = 31482470
241 + 31482229 = 31482470

Showing the first eight; more decompositions exist.
