Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978976, here are decompositions:

3 + 978973 = 978976
29 + 978947 = 978976
59 + 978917 = 978976
113 + 978863 = 978976
137 + 978839 = 978976
179 + 978797 = 978976
227 + 978749 = 978976
233 + 978743 = 978976

Showing the first eight; more decompositions exist.
