Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463180, here are decompositions:

13 + 31463167 = 31463180
19 + 31463161 = 31463180
43 + 31463137 = 31463180
97 + 31463083 = 31463180
103 + 31463077 = 31463180
157 + 31463023 = 31463180
211 + 31462969 = 31463180
271 + 31462909 = 31463180

Showing the first eight; more decompositions exist.
