Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598118, here are decompositions:

17 + 31598101 = 31598118
61 + 31598057 = 31598118
89 + 31598029 = 31598118
107 + 31598011 = 31598118
109 + 31598009 = 31598118
131 + 31597987 = 31598118
157 + 31597961 = 31598118
191 + 31597927 = 31598118

Showing the first eight; more decompositions exist.
