Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977220, here are decompositions:

11 + 977209 = 977220
17 + 977203 = 977220
29 + 977191 = 977220
37 + 977183 = 977220
53 + 977167 = 977220
71 + 977149 = 977220
73 + 977147 = 977220
113 + 977107 = 977220

Showing the first eight; more decompositions exist.
