Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612224, here are decompositions:

23 + 31612201 = 31612224
73 + 31612151 = 31612224
103 + 31612121 = 31612224
181 + 31612043 = 31612224
211 + 31612013 = 31612224
227 + 31611997 = 31612224
283 + 31611941 = 31612224
307 + 31611917 = 31612224

Showing the first eight; more decompositions exist.
