Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463174, here are decompositions:

7 + 31463167 = 31463174
13 + 31463161 = 31463174
37 + 31463137 = 31463174
97 + 31463077 = 31463174
151 + 31463023 = 31463174
241 + 31462933 = 31463174
277 + 31462897 = 31463174
367 + 31462807 = 31463174

Showing the first eight; more decompositions exist.
