Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620016, here are decompositions:

3 + 31620013 = 31620016
23 + 31619993 = 31620016
167 + 31619849 = 31620016
173 + 31619843 = 31620016
227 + 31619789 = 31620016
257 + 31619759 = 31620016
293 + 31619723 = 31620016
347 + 31619669 = 31620016

Showing the first eight; more decompositions exist.
