Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612532, here are decompositions:

19 + 31612513 = 31612532
79 + 31612453 = 31612532
103 + 31612429 = 31612532
109 + 31612423 = 31612532
151 + 31612381 = 31612532
163 + 31612369 = 31612532
181 + 31612351 = 31612532
223 + 31612309 = 31612532

Showing the first eight; more decompositions exist.
