Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636140, here are decompositions:

3 + 8636137 = 8636140
11 + 8636129 = 8636140
17 + 8636123 = 8636140
47 + 8636093 = 8636140
53 + 8636087 = 8636140
59 + 8636081 = 8636140
83 + 8636057 = 8636140
101 + 8636039 = 8636140

Showing the first eight; more decompositions exist.
