Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988078, here are decompositions:

11 + 988067 = 988078
17 + 988061 = 988078
71 + 988007 = 988078
107 + 987971 = 988078
137 + 987941 = 988078
149 + 987929 = 988078
167 + 987911 = 988078
227 + 987851 = 988078

Showing the first eight; more decompositions exist.
