Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988226, here are decompositions:

7 + 988219 = 988226
13 + 988213 = 988226
79 + 988147 = 988226
97 + 988129 = 988226
157 + 988069 = 988226
193 + 988033 = 988226
229 + 987997 = 988226
313 + 987913 = 988226

Showing the first eight; more decompositions exist.
