Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603164, here are decompositions:

7 + 31603157 = 31603164
17 + 31603147 = 31603164
23 + 31603141 = 31603164
41 + 31603123 = 31603164
53 + 31603111 = 31603164
137 + 31603027 = 31603164
191 + 31602973 = 31603164
233 + 31602931 = 31603164

Showing the first eight; more decompositions exist.
