Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622454, here are decompositions:

107 + 31622347 = 31622454
167 + 31622287 = 31622454
173 + 31622281 = 31622454
181 + 31622273 = 31622454
197 + 31622257 = 31622454
271 + 31622183 = 31622454
307 + 31622147 = 31622454
313 + 31622141 = 31622454

Showing the first eight; more decompositions exist.
