Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636112, here are decompositions:

5 + 8636107 = 8636112
19 + 8636093 = 8636112
29 + 8636083 = 8636112
31 + 8636081 = 8636112
73 + 8636039 = 8636112
113 + 8635999 = 8636112
131 + 8635981 = 8636112
179 + 8635933 = 8636112

Showing the first eight; more decompositions exist.
