Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463994, here are decompositions:

31 + 31463963 = 31463994
53 + 31463941 = 31463994
73 + 31463921 = 31463994
83 + 31463911 = 31463994
97 + 31463897 = 31463994
101 + 31463893 = 31463994
103 + 31463891 = 31463994
137 + 31463857 = 31463994

Showing the first eight; more decompositions exist.
