Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532270, here are decompositions:

43 + 31532227 = 31532270
61 + 31532209 = 31532270
67 + 31532203 = 31532270
103 + 31532167 = 31532270
157 + 31532113 = 31532270
181 + 31532089 = 31532270
199 + 31532071 = 31532270
349 + 31531921 = 31532270

Showing the first eight; more decompositions exist.
