Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981042, here are decompositions:

5 + 981037 = 981042
19 + 981023 = 981042
31 + 981011 = 981042
43 + 980999 = 981042
79 + 980963 = 981042
131 + 980911 = 981042
149 + 980893 = 981042
191 + 980851 = 981042

Showing the first eight; more decompositions exist.
