Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001938, here are decompositions:

5 + 1001933 = 1001938
107 + 1001831 = 1001938
131 + 1001807 = 1001938
137 + 1001801 = 1001938
251 + 1001687 = 1001938
269 + 1001669 = 1001938
317 + 1001621 = 1001938
389 + 1001549 = 1001938

Showing the first eight; more decompositions exist.
