Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532312, here are decompositions:

43 + 31532269 = 31532312
103 + 31532209 = 31532312
109 + 31532203 = 31532312
199 + 31532113 = 31532312
223 + 31532089 = 31532312
241 + 31532071 = 31532312
499 + 31531813 = 31532312
673 + 31531639 = 31532312

Showing the first eight; more decompositions exist.
