Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454090, here are decompositions:

7 + 31454083 = 31454090
13 + 31454077 = 31454090
37 + 31454053 = 31454090
67 + 31454023 = 31454090
97 + 31453993 = 31454090
181 + 31453909 = 31454090
193 + 31453897 = 31454090
211 + 31453879 = 31454090

Showing the first eight; more decompositions exist.
