Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620294, here are decompositions:

31 + 31620263 = 31620294
71 + 31620223 = 31620294
103 + 31620191 = 31620294
127 + 31620167 = 31620294
163 + 31620131 = 31620294
227 + 31620067 = 31620294
257 + 31620037 = 31620294
281 + 31620013 = 31620294

Showing the first eight; more decompositions exist.
