Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589834, here are decompositions:

7 + 31589827 = 31589834
61 + 31589773 = 31589834
97 + 31589737 = 31589834
103 + 31589731 = 31589834
127 + 31589707 = 31589834
151 + 31589683 = 31589834
223 + 31589611 = 31589834
373 + 31589461 = 31589834

Showing the first eight; more decompositions exist.
