Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001216, here are decompositions:

19 + 1001197 = 1001216
43 + 1001173 = 1001216
109 + 1001107 = 1001216
127 + 1001089 = 1001216
193 + 1001023 = 1001216
199 + 1001017 = 1001216
367 + 1000849 = 1001216
439 + 1000777 = 1001216

Showing the first eight; more decompositions exist.
