Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981016, here are decompositions:

5 + 981011 = 981016
17 + 980999 = 981016
53 + 980963 = 981016
59 + 980957 = 981016
107 + 980909 = 981016
467 + 980549 = 981016
557 + 980459 = 981016
593 + 980423 = 981016

Showing the first eight; more decompositions exist.
