Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978800, here are decompositions:

3 + 978797 = 978800
73 + 978727 = 978800
103 + 978697 = 978800
157 + 978643 = 978800
181 + 978619 = 978800
337 + 978463 = 978800
373 + 978427 = 978800
397 + 978403 = 978800

Showing the first eight; more decompositions exist.
