Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454354, here are decompositions:

3 + 31454351 = 31454354
157 + 31454197 = 31454354
163 + 31454191 = 31454354
193 + 31454161 = 31454354
271 + 31454083 = 31454354
277 + 31454077 = 31454354
331 + 31454023 = 31454354
397 + 31453957 = 31454354

Showing the first eight; more decompositions exist.
