Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991002, here are decompositions:

13 + 990989 = 991002
29 + 990973 = 991002
41 + 990961 = 991002
79 + 990923 = 991002
109 + 990893 = 991002
113 + 990889 = 991002
151 + 990851 = 991002
193 + 990809 = 991002

Showing the first eight; more decompositions exist.
