Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589136, here are decompositions:

17 + 31589119 = 31589136
37 + 31589099 = 31589136
67 + 31589069 = 31589136
79 + 31589057 = 31589136
109 + 31589027 = 31589136
157 + 31588979 = 31589136
179 + 31588957 = 31589136
193 + 31588943 = 31589136

Showing the first eight; more decompositions exist.
