Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981094, here are decompositions:

3 + 981091 = 981094
17 + 981077 = 981094
71 + 981023 = 981094
83 + 981011 = 981094
131 + 980963 = 981094
137 + 980957 = 981094
173 + 980921 = 981094
197 + 980897 = 981094

Showing the first eight; more decompositions exist.
