Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463924, here are decompositions:

3 + 31463921 = 31463924
13 + 31463911 = 31463924
31 + 31463893 = 31463924
67 + 31463857 = 31463924
97 + 31463827 = 31463924
127 + 31463797 = 31463924
157 + 31463767 = 31463924
181 + 31463743 = 31463924

Showing the first eight; more decompositions exist.
