Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620354, here are decompositions:

11 + 31620343 = 31620354
37 + 31620317 = 31620354
53 + 31620301 = 31620354
131 + 31620223 = 31620354
151 + 31620203 = 31620354
163 + 31620191 = 31620354
223 + 31620131 = 31620354
317 + 31620037 = 31620354

Showing the first eight; more decompositions exist.
