Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454022, here are decompositions:

29 + 31453993 = 31454022
31 + 31453991 = 31454022
53 + 31453969 = 31454022
79 + 31453943 = 31454022
113 + 31453909 = 31454022
139 + 31453883 = 31454022
181 + 31453841 = 31454022
199 + 31453823 = 31454022

Showing the first eight; more decompositions exist.
