Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981030, here are decompositions:

7 + 981023 = 981030
13 + 981017 = 981030
19 + 981011 = 981030
31 + 980999 = 981030
67 + 980963 = 981030
73 + 980957 = 981030
109 + 980921 = 981030
131 + 980899 = 981030

Showing the first eight; more decompositions exist.
