Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543834, here are decompositions:

5 + 31543829 = 31543834
17 + 31543817 = 31543834
71 + 31543763 = 31543834
83 + 31543751 = 31543834
137 + 31543697 = 31543834
173 + 31543661 = 31543834
191 + 31543643 = 31543834
263 + 31543571 = 31543834

Showing the first eight; more decompositions exist.
