Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454060, here are decompositions:

7 + 31454053 = 31454060
37 + 31454023 = 31454060
67 + 31453993 = 31454060
103 + 31453957 = 31454060
151 + 31453909 = 31454060
163 + 31453897 = 31454060
181 + 31453879 = 31454060
193 + 31453867 = 31454060

Showing the first eight; more decompositions exist.
