Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523270, here are decompositions:

3 + 31523267 = 31523270
19 + 31523251 = 31523270
43 + 31523227 = 31523270
61 + 31523209 = 31523270
109 + 31523161 = 31523270
127 + 31523143 = 31523270
139 + 31523131 = 31523270
151 + 31523119 = 31523270

Showing the first eight; more decompositions exist.
