Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988208, here are decompositions:

61 + 988147 = 988208
79 + 988129 = 988208
97 + 988111 = 988208
139 + 988069 = 988208
157 + 988051 = 988208
211 + 987997 = 988208
229 + 987979 = 988208
577 + 987631 = 988208

Showing the first eight; more decompositions exist.
