Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527834, here are decompositions:

5 + 31527829 = 31527834
7 + 31527827 = 31527834
17 + 31527817 = 31527834
47 + 31527787 = 31527834
53 + 31527781 = 31527834
131 + 31527703 = 31527834
137 + 31527697 = 31527834
157 + 31527677 = 31527834

Showing the first eight; more decompositions exist.
