Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612120, here are decompositions:

11 + 31612109 = 31612120
41 + 31612079 = 31612120
107 + 31612013 = 31612120
179 + 31611941 = 31612120
227 + 31611893 = 31612120
251 + 31611869 = 31612120
269 + 31611851 = 31612120
317 + 31611803 = 31612120

Showing the first eight; more decompositions exist.
