Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688886, here are decompositions:

23 + 8688863 = 8688886
179 + 8688707 = 8688886
257 + 8688629 = 8688886
293 + 8688593 = 8688886
317 + 8688569 = 8688886
359 + 8688527 = 8688886
389 + 8688497 = 8688886
449 + 8688437 = 8688886

Showing the first eight; more decompositions exist.
