Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001228, here are decompositions:

31 + 1001197 = 1001228
37 + 1001191 = 1001228
139 + 1001089 = 1001228
211 + 1001017 = 1001228
229 + 1000999 = 1001228
307 + 1000921 = 1001228
367 + 1000861 = 1001228
379 + 1000849 = 1001228

Showing the first eight; more decompositions exist.
