Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619222, here are decompositions:

13 + 31619209 = 31619222
31 + 31619191 = 31619222
43 + 31619179 = 31619222
79 + 31619143 = 31619222
181 + 31619041 = 31619222
223 + 31618999 = 31619222
241 + 31618981 = 31619222
331 + 31618891 = 31619222

Showing the first eight; more decompositions exist.
