Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981150, here are decompositions:

11 + 981139 = 981150
13 + 981137 = 981150
17 + 981133 = 981150
59 + 981091 = 981150
73 + 981077 = 981150
83 + 981067 = 981150
89 + 981061 = 981150
101 + 981049 = 981150

Showing the first eight; more decompositions exist.
