Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001636, here are decompositions:

7 + 1001629 = 1001636
43 + 1001593 = 1001636
67 + 1001569 = 1001636
73 + 1001563 = 1001636
109 + 1001527 = 1001636
283 + 1001353 = 1001636
313 + 1001323 = 1001636
439 + 1001197 = 1001636

Showing the first eight; more decompositions exist.
