Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977838, here are decompositions:

7 + 977831 = 977838
19 + 977819 = 977838
47 + 977791 = 977838
157 + 977681 = 977838
167 + 977671 = 977838
227 + 977611 = 977838
229 + 977609 = 977838
271 + 977567 = 977838

Showing the first eight; more decompositions exist.
