Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977888, here are decompositions:

7 + 977881 = 977888
97 + 977791 = 977888
127 + 977761 = 977888
277 + 977611 = 977888
349 + 977539 = 977888
367 + 977521 = 977888
619 + 977269 = 977888
631 + 977257 = 977888

Showing the first eight; more decompositions exist.
