Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622162, here are decompositions:

31 + 31622131 = 31622162
43 + 31622119 = 31622162
181 + 31621981 = 31622162
199 + 31621963 = 31622162
283 + 31621879 = 31622162
331 + 31621831 = 31622162
409 + 31621753 = 31622162
541 + 31621621 = 31622162

Showing the first eight; more decompositions exist.
