Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589324, here are decompositions:

3 + 31589321 = 31589324
7 + 31589317 = 31589324
31 + 31589293 = 31589324
37 + 31589287 = 31589324
73 + 31589251 = 31589324
127 + 31589197 = 31589324
157 + 31589167 = 31589324
307 + 31589017 = 31589324

Showing the first eight; more decompositions exist.
