Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669836, here are decompositions:

5 + 8669831 = 8669836
59 + 8669777 = 8669836
167 + 8669669 = 8669836
179 + 8669657 = 8669836
293 + 8669543 = 8669836
347 + 8669489 = 8669836
353 + 8669483 = 8669836
359 + 8669477 = 8669836

Showing the first eight; more decompositions exist.
