Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589764, here are decompositions:

5 + 31589759 = 31589764
53 + 31589711 = 31589764
71 + 31589693 = 31589764
131 + 31589633 = 31589764
197 + 31589567 = 31589764
251 + 31589513 = 31589764
281 + 31589483 = 31589764
431 + 31589333 = 31589764

Showing the first eight; more decompositions exist.
