Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454024, here are decompositions:

31 + 31453993 = 31454024
67 + 31453957 = 31454024
127 + 31453897 = 31454024
157 + 31453867 = 31454024
211 + 31453813 = 31454024
241 + 31453783 = 31454024
313 + 31453711 = 31454024
373 + 31453651 = 31454024

Showing the first eight; more decompositions exist.
