Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622270, here are decompositions:

13 + 31622257 = 31622270
103 + 31622167 = 31622270
139 + 31622131 = 31622270
151 + 31622119 = 31622270
157 + 31622113 = 31622270
223 + 31622047 = 31622270
307 + 31621963 = 31622270
313 + 31621957 = 31622270

Showing the first eight; more decompositions exist.
