Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463184, here are decompositions:

17 + 31463167 = 31463184
23 + 31463161 = 31463184
37 + 31463147 = 31463184
47 + 31463137 = 31463184
61 + 31463123 = 31463184
97 + 31463087 = 31463184
101 + 31463083 = 31463184
107 + 31463077 = 31463184

Showing the first eight; more decompositions exist.
