Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528164, here are decompositions:

7 + 31528157 = 31528164
13 + 31528151 = 31528164
37 + 31528127 = 31528164
43 + 31528121 = 31528164
53 + 31528111 = 31528164
61 + 31528103 = 31528164
71 + 31528093 = 31528164
97 + 31528067 = 31528164

Showing the first eight; more decompositions exist.
