Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463198, here are decompositions:

31 + 31463167 = 31463198
37 + 31463161 = 31463198
61 + 31463137 = 31463198
229 + 31462969 = 31463198
367 + 31462831 = 31463198
439 + 31462759 = 31463198
607 + 31462591 = 31463198
619 + 31462579 = 31463198

Showing the first eight; more decompositions exist.
