Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622258, here are decompositions:

79 + 31622179 = 31622258
127 + 31622131 = 31622258
139 + 31622119 = 31622258
211 + 31622047 = 31622258
277 + 31621981 = 31622258
379 + 31621879 = 31622258
607 + 31621651 = 31622258
727 + 31621531 = 31622258

Showing the first eight; more decompositions exist.
