Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637206, here are decompositions:

3 + 8637203 = 8637206
43 + 8637163 = 8637206
73 + 8637133 = 8637206
103 + 8637103 = 8637206
139 + 8637067 = 8637206
199 + 8637007 = 8637206
283 + 8636923 = 8637206
307 + 8636899 = 8637206

Showing the first eight; more decompositions exist.
