Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522222, here are decompositions:

3 + 31522219 = 31522222
41 + 31522181 = 31522222
131 + 31522091 = 31522222
269 + 31521953 = 31522222
359 + 31521863 = 31522222
509 + 31521713 = 31522222
773 + 31521449 = 31522222
863 + 31521359 = 31522222

Showing the first eight; more decompositions exist.
