Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606000, here are decompositions:

17 + 31605983 = 31606000
29 + 31605971 = 31606000
47 + 31605953 = 31606000
71 + 31605929 = 31606000
191 + 31605809 = 31606000
197 + 31605803 = 31606000
227 + 31605773 = 31606000
281 + 31605719 = 31606000

Showing the first eight; more decompositions exist.
