Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454046, here are decompositions:

23 + 31454023 = 31454046
53 + 31453993 = 31454046
89 + 31453957 = 31454046
103 + 31453943 = 31454046
137 + 31453909 = 31454046
149 + 31453897 = 31454046
163 + 31453883 = 31454046
167 + 31453879 = 31454046

Showing the first eight; more decompositions exist.
