Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598124, here are decompositions:

23 + 31598101 = 31598124
67 + 31598057 = 31598124
97 + 31598027 = 31598124
113 + 31598011 = 31598124
127 + 31597997 = 31598124
137 + 31597987 = 31598124
163 + 31597961 = 31598124
191 + 31597933 = 31598124

Showing the first eight; more decompositions exist.
