Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988272, here are decompositions:

29 + 988243 = 988272
41 + 988231 = 988272
53 + 988219 = 988272
59 + 988213 = 988272
73 + 988199 = 988272
163 + 988109 = 988272
179 + 988093 = 988272
211 + 988061 = 988272

Showing the first eight; more decompositions exist.
