Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009998, here are decompositions:

5 + 1009993 = 1009998
7 + 1009991 = 1009998
47 + 1009951 = 1009998
61 + 1009937 = 1009998
71 + 1009927 = 1009998
89 + 1009909 = 1009998
97 + 1009901 = 1009998
139 + 1009859 = 1009998

Showing the first eight; more decompositions exist.
