Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589300, here are decompositions:

3 + 31589297 = 31589300
7 + 31589293 = 31589300
13 + 31589287 = 31589300
103 + 31589197 = 31589300
163 + 31589137 = 31589300
181 + 31589119 = 31589300
283 + 31589017 = 31589300
307 + 31588993 = 31589300

Showing the first eight; more decompositions exist.
