Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636220, here are decompositions:

53 + 8636167 = 8636220
79 + 8636141 = 8636220
83 + 8636137 = 8636220
97 + 8636123 = 8636220
113 + 8636107 = 8636220
127 + 8636093 = 8636220
137 + 8636083 = 8636220
139 + 8636081 = 8636220

Showing the first eight; more decompositions exist.
