Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612026, here are decompositions:

13 + 31612013 = 31612026
29 + 31611997 = 31612026
109 + 31611917 = 31612026
157 + 31611869 = 31612026
197 + 31611829 = 31612026
223 + 31611803 = 31612026
269 + 31611757 = 31612026
293 + 31611733 = 31612026

Showing the first eight; more decompositions exist.
