Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981102, here are decompositions:

11 + 981091 = 981102
29 + 981073 = 981102
41 + 981061 = 981102
53 + 981049 = 981102
79 + 981023 = 981102
103 + 980999 = 981102
139 + 980963 = 981102
181 + 980921 = 981102

Showing the first eight; more decompositions exist.
