Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589198, here are decompositions:

31 + 31589167 = 31589198
61 + 31589137 = 31589198
79 + 31589119 = 31589198
181 + 31589017 = 31589198
241 + 31588957 = 31589198
271 + 31588927 = 31589198
499 + 31588699 = 31589198
541 + 31588657 = 31589198

Showing the first eight; more decompositions exist.
