Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589932, here are decompositions:

41 + 31589891 = 31589932
71 + 31589861 = 31589932
89 + 31589843 = 31589932
113 + 31589819 = 31589932
173 + 31589759 = 31589932
239 + 31589693 = 31589932
419 + 31589513 = 31589932
449 + 31589483 = 31589932

Showing the first eight; more decompositions exist.
