Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755628, here are decompositions:

127 + 8755501 = 8755628
229 + 8755399 = 8755628
307 + 8755321 = 8755628
331 + 8755297 = 8755628
337 + 8755291 = 8755628
397 + 8755231 = 8755628
439 + 8755189 = 8755628
487 + 8755141 = 8755628

Showing the first eight; more decompositions exist.
