Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977790, here are decompositions:

29 + 977761 = 977790
43 + 977747 = 977790
67 + 977723 = 977790
71 + 977719 = 977790
97 + 977693 = 977790
109 + 977681 = 977790
179 + 977611 = 977790
181 + 977609 = 977790

Showing the first eight; more decompositions exist.
