Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981106, here are decompositions:

29 + 981077 = 981106
83 + 981023 = 981106
89 + 981017 = 981106
107 + 980999 = 981106
149 + 980957 = 981106
197 + 980909 = 981106
389 + 980717 = 981106
419 + 980687 = 981106

Showing the first eight; more decompositions exist.
