Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001984, here are decompositions:

3 + 1001981 = 1001984
7 + 1001977 = 1001984
31 + 1001953 = 1001984
37 + 1001947 = 1001984
43 + 1001941 = 1001984
73 + 1001911 = 1001984
163 + 1001821 = 1001984
241 + 1001743 = 1001984

Showing the first eight; more decompositions exist.
