Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463854, here are decompositions:

5 + 31463849 = 31463854
11 + 31463843 = 31463854
47 + 31463807 = 31463854
137 + 31463717 = 31463854
173 + 31463681 = 31463854
263 + 31463591 = 31463854
347 + 31463507 = 31463854
467 + 31463387 = 31463854

Showing the first eight; more decompositions exist.
