Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479470, here are decompositions:

3 + 31479467 = 31479470
13 + 31479457 = 31479470
31 + 31479439 = 31479470
163 + 31479307 = 31479470
181 + 31479289 = 31479470
193 + 31479277 = 31479470
199 + 31479271 = 31479470
229 + 31479241 = 31479470

Showing the first eight; more decompositions exist.
