Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589632, here are decompositions:

71 + 31589561 = 31589632
149 + 31589483 = 31589632
293 + 31589339 = 31589632
311 + 31589321 = 31589632
449 + 31589183 = 31589632
563 + 31589069 = 31589632
653 + 31588979 = 31589632
953 + 31588679 = 31589632

Showing the first eight; more decompositions exist.
