Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531614, here are decompositions:

131 + 31531483 = 31531614
157 + 31531457 = 31531614
193 + 31531421 = 31531614
197 + 31531417 = 31531614
211 + 31531403 = 31531614
311 + 31531303 = 31531614
313 + 31531301 = 31531614
347 + 31531267 = 31531614

Showing the first eight; more decompositions exist.
