Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981116, here are decompositions:

43 + 981073 = 981116
67 + 981049 = 981116
79 + 981037 = 981116
223 + 980893 = 981116
229 + 980887 = 981116
313 + 980803 = 981116
397 + 980719 = 981116
439 + 980677 = 981116

Showing the first eight; more decompositions exist.
