Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622358, here are decompositions:

11 + 31622347 = 31622358
71 + 31622287 = 31622358
101 + 31622257 = 31622358
151 + 31622207 = 31622358
179 + 31622179 = 31622358
191 + 31622167 = 31622358
211 + 31622147 = 31622358
227 + 31622131 = 31622358

Showing the first eight; more decompositions exist.
