Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607136, here are decompositions:

89 + 31607047 = 31607136
97 + 31607039 = 31607136
139 + 31606997 = 31607136
157 + 31606979 = 31607136
163 + 31606973 = 31607136
173 + 31606963 = 31607136
179 + 31606957 = 31607136
193 + 31606943 = 31607136

Showing the first eight; more decompositions exist.
