Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001398, here are decompositions:

11 + 1001387 = 1001398
17 + 1001381 = 1001398
29 + 1001369 = 1001398
71 + 1001327 = 1001398
107 + 1001291 = 1001398
131 + 1001267 = 1001398
179 + 1001219 = 1001398
239 + 1001159 = 1001398

Showing the first eight; more decompositions exist.
