Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598098, here are decompositions:

41 + 31598057 = 31598098
71 + 31598027 = 31598098
89 + 31598009 = 31598098
101 + 31597997 = 31598098
137 + 31597961 = 31598098
359 + 31597739 = 31598098
401 + 31597697 = 31598098
557 + 31597541 = 31598098

Showing the first eight; more decompositions exist.
