Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981076, here are decompositions:

3 + 981073 = 981076
53 + 981023 = 981076
59 + 981017 = 981076
113 + 980963 = 981076
167 + 980909 = 981076
179 + 980897 = 981076
347 + 980729 = 981076
359 + 980717 = 981076

Showing the first eight; more decompositions exist.
