Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607088, here are decompositions:

41 + 31607047 = 31607088
109 + 31606979 = 31607088
131 + 31606957 = 31607088
137 + 31606951 = 31607088
157 + 31606931 = 31607088
241 + 31606847 = 31607088
277 + 31606811 = 31607088
347 + 31606741 = 31607088

Showing the first eight; more decompositions exist.
