Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455302, here are decompositions:

3 + 31455299 = 31455302
31 + 31455271 = 31455302
79 + 31455223 = 31455302
163 + 31455139 = 31455302
181 + 31455121 = 31455302
199 + 31455103 = 31455302
271 + 31455031 = 31455302
331 + 31454971 = 31455302

Showing the first eight; more decompositions exist.
