Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589740, here are decompositions:

3 + 31589737 = 31589740
29 + 31589711 = 31589740
47 + 31589693 = 31589740
107 + 31589633 = 31589740
173 + 31589567 = 31589740
179 + 31589561 = 31589740
227 + 31589513 = 31589740
257 + 31589483 = 31589740

Showing the first eight; more decompositions exist.
