Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598136, here are decompositions:

79 + 31598057 = 31598136
103 + 31598033 = 31598136
107 + 31598029 = 31598136
109 + 31598027 = 31598136
127 + 31598009 = 31598136
139 + 31597997 = 31598136
149 + 31597987 = 31598136
223 + 31597913 = 31598136

Showing the first eight; more decompositions exist.
