Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008998, here are decompositions:

7 + 1008991 = 1008998
19 + 1008979 = 1008998
61 + 1008937 = 1008998
97 + 1008901 = 1008998
127 + 1008871 = 1008998
139 + 1008859 = 1008998
181 + 1008817 = 1008998
409 + 1008589 = 1008998

Showing the first eight; more decompositions exist.
