Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737288, here are decompositions:

11 + 8737277 = 8737288
17 + 8737271 = 8737288
41 + 8737247 = 8737288
89 + 8737199 = 8737288
149 + 8737139 = 8737288
191 + 8737097 = 8737288
227 + 8737061 = 8737288
239 + 8737049 = 8737288

Showing the first eight; more decompositions exist.
