Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536804, here are decompositions:

11 + 31536793 = 31536804
31 + 31536773 = 31536804
71 + 31536733 = 31536804
73 + 31536731 = 31536804
97 + 31536707 = 31536804
107 + 31536697 = 31536804
191 + 31536613 = 31536804
197 + 31536607 = 31536804

Showing the first eight; more decompositions exist.
