Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454038, here are decompositions:

41 + 31453997 = 31454038
47 + 31453991 = 31454038
107 + 31453931 = 31454038
197 + 31453841 = 31454038
311 + 31453727 = 31454038
359 + 31453679 = 31454038
461 + 31453577 = 31454038
467 + 31453571 = 31454038

Showing the first eight; more decompositions exist.
