Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988212, here are decompositions:

13 + 988199 = 988212
83 + 988129 = 988212
101 + 988111 = 988212
103 + 988109 = 988212
151 + 988061 = 988212
179 + 988033 = 988212
191 + 988021 = 988212
229 + 987983 = 988212

Showing the first eight; more decompositions exist.
