Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977928, here are decompositions:

5 + 977923 = 977928
31 + 977897 = 977928
47 + 977881 = 977928
67 + 977861 = 977928
79 + 977849 = 977928
97 + 977831 = 977928
109 + 977819 = 977928
137 + 977791 = 977928

Showing the first eight; more decompositions exist.
