Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637242, here are decompositions:

79 + 8637163 = 8637242
109 + 8637133 = 8637242
139 + 8637103 = 8637242
151 + 8637091 = 8637242
181 + 8637061 = 8637242
283 + 8636959 = 8637242
331 + 8636911 = 8637242
349 + 8636893 = 8637242

Showing the first eight; more decompositions exist.
