Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001286, here are decompositions:

7 + 1001279 = 1001286
19 + 1001267 = 1001286
67 + 1001219 = 1001286
89 + 1001197 = 1001286
109 + 1001177 = 1001286
113 + 1001173 = 1001286
127 + 1001159 = 1001286
163 + 1001123 = 1001286

Showing the first eight; more decompositions exist.
