Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563834, here are decompositions:

7 + 31563827 = 31563834
17 + 31563817 = 31563834
41 + 31563793 = 31563834
47 + 31563787 = 31563834
61 + 31563773 = 31563834
97 + 31563737 = 31563834
101 + 31563733 = 31563834
151 + 31563683 = 31563834

Showing the first eight; more decompositions exist.
