Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523234, here are decompositions:

3 + 31523231 = 31523234
7 + 31523227 = 31523234
13 + 31523221 = 31523234
73 + 31523161 = 31523234
103 + 31523131 = 31523234
181 + 31523053 = 31523234
283 + 31522951 = 31523234
487 + 31522747 = 31523234

Showing the first eight; more decompositions exist.
