Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589776, here are decompositions:

3 + 31589773 = 31589776
5 + 31589771 = 31589776
17 + 31589759 = 31589776
83 + 31589693 = 31589776
263 + 31589513 = 31589776
293 + 31589483 = 31589776
353 + 31589423 = 31589776
443 + 31589333 = 31589776

Showing the first eight; more decompositions exist.
