Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637182, here are decompositions:

3 + 8637179 = 8637182
19 + 8637163 = 8637182
31 + 8637151 = 8637182
79 + 8637103 = 8637182
193 + 8636989 = 8637182
223 + 8636959 = 8637182
271 + 8636911 = 8637182
283 + 8636899 = 8637182

Showing the first eight; more decompositions exist.
