Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454310, here are decompositions:

47 + 31454263 = 31454310
61 + 31454249 = 31454310
89 + 31454221 = 31454310
109 + 31454201 = 31454310
113 + 31454197 = 31454310
149 + 31454161 = 31454310
163 + 31454147 = 31454310
193 + 31454117 = 31454310

Showing the first eight; more decompositions exist.
