Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607082, here are decompositions:

43 + 31607039 = 31607082
103 + 31606979 = 31607082
109 + 31606973 = 31607082
131 + 31606951 = 31607082
139 + 31606943 = 31607082
151 + 31606931 = 31607082
163 + 31606919 = 31607082
179 + 31606903 = 31607082

Showing the first eight; more decompositions exist.
