Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977778, here are decompositions:

17 + 977761 = 977778
31 + 977747 = 977778
59 + 977719 = 977778
97 + 977681 = 977778
107 + 977671 = 977778
149 + 977629 = 977778
167 + 977611 = 977778
211 + 977567 = 977778

Showing the first eight; more decompositions exist.
