Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981152, here are decompositions:

13 + 981139 = 981152
19 + 981133 = 981152
61 + 981091 = 981152
79 + 981073 = 981152
103 + 981049 = 981152
241 + 980911 = 981152
349 + 980803 = 981152
379 + 980773 = 981152

Showing the first eight; more decompositions exist.
