Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977878, here are decompositions:

17 + 977861 = 977878
29 + 977849 = 977878
47 + 977831 = 977878
59 + 977819 = 977878
131 + 977747 = 977878
197 + 977681 = 977878
269 + 977609 = 977878
311 + 977567 = 977878

Showing the first eight; more decompositions exist.
