Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001278, here are decompositions:

11 + 1001267 = 1001278
41 + 1001237 = 1001278
59 + 1001219 = 1001278
101 + 1001177 = 1001278
191 + 1001087 = 1001278
197 + 1001081 = 1001278
251 + 1001027 = 1001278
347 + 1000931 = 1001278

Showing the first eight; more decompositions exist.
