Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636908, here are decompositions:

89 + 8636819 = 8636908
107 + 8636801 = 8636908
149 + 8636759 = 8636908
167 + 8636741 = 8636908
281 + 8636627 = 8636908
317 + 8636591 = 8636908
359 + 8636549 = 8636908
521 + 8636387 = 8636908

Showing the first eight; more decompositions exist.
