Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978936, here are decompositions:

5 + 978931 = 978936
19 + 978917 = 978936
29 + 978907 = 978936
53 + 978883 = 978936
73 + 978863 = 978936
83 + 978853 = 978936
97 + 978839 = 978936
137 + 978799 = 978936

Showing the first eight; more decompositions exist.
