Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612152, here are decompositions:

31 + 31612121 = 31612152
43 + 31612109 = 31612152
71 + 31612081 = 31612152
73 + 31612079 = 31612152
83 + 31612069 = 31612152
109 + 31612043 = 31612152
139 + 31612013 = 31612152
211 + 31611941 = 31612152

Showing the first eight; more decompositions exist.
