Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988216, here are decompositions:

3 + 988213 = 988216
17 + 988199 = 988216
59 + 988157 = 988216
107 + 988109 = 988216
149 + 988067 = 988216
233 + 987983 = 988216
347 + 987869 = 988216
419 + 987797 = 988216

Showing the first eight; more decompositions exist.
