Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977988, here are decompositions:

17 + 977971 = 977988
61 + 977927 = 977988
107 + 977881 = 977988
127 + 977861 = 977988
139 + 977849 = 977988
157 + 977831 = 977988
197 + 977791 = 977988
227 + 977761 = 977988

Showing the first eight; more decompositions exist.
