Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001992, here are decompositions:

3 + 1001989 = 1001992
11 + 1001981 = 1001992
59 + 1001933 = 1001992
191 + 1001801 = 1001992
269 + 1001723 = 1001992
353 + 1001639 = 1001992
443 + 1001549 = 1001992
461 + 1001531 = 1001992

Showing the first eight; more decompositions exist.
