Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622312, here are decompositions:

19 + 31622293 = 31622312
31 + 31622281 = 31622312
181 + 31622131 = 31622312
193 + 31622119 = 31622312
199 + 31622113 = 31622312
331 + 31621981 = 31622312
349 + 31621963 = 31622312
433 + 31621879 = 31622312

Showing the first eight; more decompositions exist.
