Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622306, here are decompositions:

13 + 31622293 = 31622306
19 + 31622287 = 31622306
127 + 31622179 = 31622306
139 + 31622167 = 31622306
193 + 31622113 = 31622306
349 + 31621957 = 31622306
409 + 31621897 = 31622306
613 + 31621693 = 31622306

Showing the first eight; more decompositions exist.
