Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589724, here are decompositions:

13 + 31589711 = 31589724
17 + 31589707 = 31589724
31 + 31589693 = 31589724
41 + 31589683 = 31589724
113 + 31589611 = 31589724
157 + 31589567 = 31589724
163 + 31589561 = 31589724
211 + 31589513 = 31589724

Showing the first eight; more decompositions exist.
