Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612048, here are decompositions:

5 + 31612043 = 31612048
107 + 31611941 = 31612048
131 + 31611917 = 31612048
137 + 31611911 = 31612048
179 + 31611869 = 31612048
197 + 31611851 = 31612048
311 + 31611737 = 31612048
389 + 31611659 = 31612048

Showing the first eight; more decompositions exist.
