Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454222, here are decompositions:

3 + 31454219 = 31454222
31 + 31454191 = 31454222
61 + 31454161 = 31454222
73 + 31454149 = 31454222
139 + 31454083 = 31454222
199 + 31454023 = 31454222
229 + 31453993 = 31454222
313 + 31453909 = 31454222

Showing the first eight; more decompositions exist.
