Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612032, here are decompositions:

19 + 31612013 = 31612032
139 + 31611893 = 31612032
149 + 31611883 = 31612032
163 + 31611869 = 31612032
181 + 31611851 = 31612032
191 + 31611841 = 31612032
229 + 31611803 = 31612032
271 + 31611761 = 31612032

Showing the first eight; more decompositions exist.
