Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455834, here are decompositions:

5 + 31455829 = 31455834
13 + 31455821 = 31455834
31 + 31455803 = 31455834
73 + 31455761 = 31455834
83 + 31455751 = 31455834
107 + 31455727 = 31455834
131 + 31455703 = 31455834
197 + 31455637 = 31455834

Showing the first eight; more decompositions exist.
