Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977772, here are decompositions:

11 + 977761 = 977772
53 + 977719 = 977772
79 + 977693 = 977772
101 + 977671 = 977772
163 + 977609 = 977772
179 + 977593 = 977772
181 + 977591 = 977772
233 + 977539 = 977772

Showing the first eight; more decompositions exist.
