Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463168, here are decompositions:

7 + 31463161 = 31463168
31 + 31463137 = 31463168
199 + 31462969 = 31463168
271 + 31462897 = 31463168
337 + 31462831 = 31463168
397 + 31462771 = 31463168
409 + 31462759 = 31463168
421 + 31462747 = 31463168

Showing the first eight; more decompositions exist.
