Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001222, here are decompositions:

3 + 1001219 = 1001222
31 + 1001191 = 1001222
181 + 1001041 = 1001222
199 + 1001023 = 1001222
223 + 1000999 = 1001222
241 + 1000981 = 1001222
373 + 1000849 = 1001222
499 + 1000723 = 1001222

Showing the first eight; more decompositions exist.
