Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454000, here are decompositions:

3 + 31453997 = 31454000
7 + 31453993 = 31454000
31 + 31453969 = 31454000
43 + 31453957 = 31454000
103 + 31453897 = 31454000
349 + 31453651 = 31454000
499 + 31453501 = 31454000
607 + 31453393 = 31454000

Showing the first eight; more decompositions exist.
