Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463070, here are decompositions:

7 + 31463063 = 31463070
47 + 31463023 = 31463070
101 + 31462969 = 31463070
137 + 31462933 = 31463070
139 + 31462931 = 31463070
173 + 31462897 = 31463070
181 + 31462889 = 31463070
193 + 31462877 = 31463070

Showing the first eight; more decompositions exist.
