Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978786, here are decompositions:

13 + 978773 = 978786
37 + 978749 = 978786
43 + 978743 = 978786
59 + 978727 = 978786
73 + 978713 = 978786
89 + 978697 = 978786
97 + 978689 = 978786
103 + 978683 = 978786

Showing the first eight; more decompositions exist.
