Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636120, here are decompositions:

13 + 8636107 = 8636120
37 + 8636083 = 8636120
139 + 8635981 = 8636120
151 + 8635969 = 8636120
193 + 8635927 = 8636120
223 + 8635897 = 8636120
271 + 8635849 = 8636120
397 + 8635723 = 8636120

Showing the first eight; more decompositions exist.
