Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454054, here are decompositions:

31 + 31454023 = 31454054
61 + 31453993 = 31454054
97 + 31453957 = 31454054
157 + 31453897 = 31454054
241 + 31453813 = 31454054
271 + 31453783 = 31454054
547 + 31453507 = 31454054
571 + 31453483 = 31454054

Showing the first eight; more decompositions exist.
