Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454030, here are decompositions:

7 + 31454023 = 31454030
37 + 31453993 = 31454030
61 + 31453969 = 31454030
73 + 31453957 = 31454030
151 + 31453879 = 31454030
163 + 31453867 = 31454030
331 + 31453699 = 31454030
379 + 31453651 = 31454030

Showing the first eight; more decompositions exist.
