Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589802, here are decompositions:

29 + 31589773 = 31589802
31 + 31589771 = 31589802
43 + 31589759 = 31589802
71 + 31589731 = 31589802
109 + 31589693 = 31589802
191 + 31589611 = 31589802
241 + 31589561 = 31589802
263 + 31589539 = 31589802

Showing the first eight; more decompositions exist.
