Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001188, here are decompositions:

11 + 1001177 = 1001188
29 + 1001159 = 1001188
101 + 1001087 = 1001188
107 + 1001081 = 1001188
257 + 1000931 = 1001188
269 + 1000919 = 1001188
281 + 1000907 = 1001188
359 + 1000829 = 1001188

Showing the first eight; more decompositions exist.
