Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506834, here are decompositions:

5 + 31506829 = 31506834
11 + 31506823 = 31506834
13 + 31506821 = 31506834
41 + 31506793 = 31506834
43 + 31506791 = 31506834
53 + 31506781 = 31506834
137 + 31506697 = 31506834
157 + 31506677 = 31506834

Showing the first eight; more decompositions exist.
