Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622408, here are decompositions:

19 + 31622389 = 31622408
31 + 31622377 = 31622408
61 + 31622347 = 31622408
127 + 31622281 = 31622408
151 + 31622257 = 31622408
229 + 31622179 = 31622408
241 + 31622167 = 31622408
277 + 31622131 = 31622408

Showing the first eight; more decompositions exist.
