Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589204, here are decompositions:

7 + 31589197 = 31589204
37 + 31589167 = 31589204
67 + 31589137 = 31589204
193 + 31589011 = 31589204
211 + 31588993 = 31589204
271 + 31588933 = 31589204
277 + 31588927 = 31589204
307 + 31588897 = 31589204

Showing the first eight; more decompositions exist.
