Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669886, here are decompositions:

7 + 8669879 = 8669886
109 + 8669777 = 8669886
229 + 8669657 = 8669886
257 + 8669629 = 8669886
263 + 8669623 = 8669886
293 + 8669593 = 8669886
359 + 8669527 = 8669886
373 + 8669513 = 8669886

Showing the first eight; more decompositions exist.
