Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635842, here are decompositions:

31 + 8635811 = 8635842
113 + 8635729 = 8635842
179 + 8635663 = 8635842
211 + 8635631 = 8635842
263 + 8635579 = 8635842
283 + 8635559 = 8635842
311 + 8635531 = 8635842
373 + 8635469 = 8635842

Showing the first eight; more decompositions exist.
