Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988222, here are decompositions:

3 + 988219 = 988222
5 + 988217 = 988222
23 + 988199 = 988222
113 + 988109 = 988222
239 + 987983 = 988222
251 + 987971 = 988222
281 + 987941 = 988222
293 + 987929 = 988222

Showing the first eight; more decompositions exist.
