Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981194, here are decompositions:

7 + 981187 = 981194
43 + 981151 = 981194
61 + 981133 = 981194
103 + 981091 = 981194
127 + 981067 = 981194
157 + 981037 = 981194
283 + 980911 = 981194
307 + 980887 = 981194

Showing the first eight; more decompositions exist.
