Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722332, here are decompositions:

29 + 8722303 = 8722332
41 + 8722291 = 8722332
109 + 8722223 = 8722332
139 + 8722193 = 8722332
163 + 8722169 = 8722332
233 + 8722099 = 8722332
239 + 8722093 = 8722332
251 + 8722081 = 8722332

Showing the first eight; more decompositions exist.
