Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607122, here are decompositions:

83 + 31607039 = 31607122
149 + 31606973 = 31607122
179 + 31606943 = 31607122
191 + 31606931 = 31607122
293 + 31606829 = 31607122
311 + 31606811 = 31607122
419 + 31606703 = 31607122
431 + 31606691 = 31607122

Showing the first eight; more decompositions exist.
