Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463112, here are decompositions:

13 + 31463099 = 31463112
29 + 31463083 = 31463112
89 + 31463023 = 31463112
179 + 31462933 = 31463112
181 + 31462931 = 31463112
211 + 31462901 = 31463112
223 + 31462889 = 31463112
281 + 31462831 = 31463112

Showing the first eight; more decompositions exist.
