Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001386, here are decompositions:

5 + 1001381 = 1001386
17 + 1001369 = 1001386
59 + 1001327 = 1001386
83 + 1001303 = 1001386
107 + 1001279 = 1001386
149 + 1001237 = 1001386
167 + 1001219 = 1001386
227 + 1001159 = 1001386

Showing the first eight; more decompositions exist.
