Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536834, here are decompositions:

5 + 31536829 = 31536834
11 + 31536823 = 31536834
13 + 31536821 = 31536834
41 + 31536793 = 31536834
61 + 31536773 = 31536834
101 + 31536733 = 31536834
103 + 31536731 = 31536834
127 + 31536707 = 31536834

Showing the first eight; more decompositions exist.
