Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453056, here are decompositions:

17 + 31453039 = 31453056
79 + 31452977 = 31453056
83 + 31452973 = 31453056
113 + 31452943 = 31453056
197 + 31452859 = 31453056
227 + 31452829 = 31453056
263 + 31452793 = 31453056
293 + 31452763 = 31453056

Showing the first eight; more decompositions exist.
