Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463178, here are decompositions:

11 + 31463167 = 31463178
17 + 31463161 = 31463178
31 + 31463147 = 31463178
41 + 31463137 = 31463178
79 + 31463099 = 31463178
101 + 31463077 = 31463178
199 + 31462979 = 31463178
269 + 31462909 = 31463178

Showing the first eight; more decompositions exist.
