Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612002, here are decompositions:

5 + 31611997 = 31612002
61 + 31611941 = 31612002
109 + 31611893 = 31612002
151 + 31611851 = 31612002
173 + 31611829 = 31612002
199 + 31611803 = 31612002
241 + 31611761 = 31612002
269 + 31611733 = 31612002

Showing the first eight; more decompositions exist.
