Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001966, here are decompositions:

13 + 1001953 = 1001966
19 + 1001947 = 1001966
127 + 1001839 = 1001966
157 + 1001809 = 1001966
223 + 1001743 = 1001966
283 + 1001683 = 1001966
307 + 1001659 = 1001966
337 + 1001629 = 1001966

Showing the first eight; more decompositions exist.
