Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977860, here are decompositions:

11 + 977849 = 977860
29 + 977831 = 977860
41 + 977819 = 977860
47 + 977813 = 977860
113 + 977747 = 977860
137 + 977723 = 977860
167 + 977693 = 977860
179 + 977681 = 977860

Showing the first eight; more decompositions exist.
