Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978980, here are decompositions:

7 + 978973 = 978980
73 + 978907 = 978980
97 + 978883 = 978980
109 + 978871 = 978980
127 + 978853 = 978980
181 + 978799 = 978980
283 + 978697 = 978980
337 + 978643 = 978980

Showing the first eight; more decompositions exist.
