Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474914, here are decompositions:

41 + 31474873 = 31474914
47 + 31474867 = 31474914
113 + 31474801 = 31474914
131 + 31474783 = 31474914
137 + 31474777 = 31474914
151 + 31474763 = 31474914
167 + 31474747 = 31474914
181 + 31474733 = 31474914

Showing the first eight; more decompositions exist.
