Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589902, here are decompositions:

11 + 31589891 = 31589902
41 + 31589861 = 31589902
59 + 31589843 = 31589902
83 + 31589819 = 31589902
131 + 31589771 = 31589902
191 + 31589711 = 31589902
269 + 31589633 = 31589902
389 + 31589513 = 31589902

Showing the first eight; more decompositions exist.
