Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454004, here are decompositions:

7 + 31453997 = 31454004
11 + 31453993 = 31454004
13 + 31453991 = 31454004
47 + 31453957 = 31454004
61 + 31453943 = 31454004
73 + 31453931 = 31454004
107 + 31453897 = 31454004
137 + 31453867 = 31454004

Showing the first eight; more decompositions exist.
