Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454346, here are decompositions:

83 + 31454263 = 31454346
97 + 31454249 = 31454346
127 + 31454219 = 31454346
149 + 31454197 = 31454346
197 + 31454149 = 31454346
199 + 31454147 = 31454346
223 + 31454123 = 31454346
229 + 31454117 = 31454346

Showing the first eight; more decompositions exist.
