Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636636, here are decompositions:

3 + 8636633 = 8636636
37 + 8636599 = 8636636
97 + 8636539 = 8636636
103 + 8636533 = 8636636
163 + 8636473 = 8636636
367 + 8636269 = 8636636
373 + 8636263 = 8636636
397 + 8636239 = 8636636

Showing the first eight; more decompositions exist.
