Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454376, here are decompositions:

113 + 31454263 = 31454376
127 + 31454249 = 31454376
157 + 31454219 = 31454376
179 + 31454197 = 31454376
227 + 31454149 = 31454376
229 + 31454147 = 31454376
293 + 31454083 = 31454376
353 + 31454023 = 31454376

Showing the first eight; more decompositions exist.
