Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454334, here are decompositions:

13 + 31454321 = 31454334
71 + 31454263 = 31454334
113 + 31454221 = 31454334
137 + 31454197 = 31454334
173 + 31454161 = 31454334
211 + 31454123 = 31454334
251 + 31454083 = 31454334
257 + 31454077 = 31454334

Showing the first eight; more decompositions exist.
