Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636142, here are decompositions:

5 + 8636137 = 8636142
13 + 8636129 = 8636142
19 + 8636123 = 8636142
59 + 8636083 = 8636142
61 + 8636081 = 8636142
103 + 8636039 = 8636142
173 + 8635969 = 8636142
191 + 8635951 = 8636142

Showing the first eight; more decompositions exist.
