Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978938, here are decompositions:

7 + 978931 = 978938
31 + 978907 = 978938
67 + 978871 = 978938
139 + 978799 = 978938
211 + 978727 = 978938
241 + 978697 = 978938
397 + 978541 = 978938
601 + 978337 = 978938

Showing the first eight; more decompositions exist.
