Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641206, here are decompositions:

19 + 8641187 = 8641206
59 + 8641147 = 8641206
73 + 8641133 = 8641206
109 + 8641097 = 8641206
113 + 8641093 = 8641206
127 + 8641079 = 8641206
199 + 8641007 = 8641206
229 + 8640977 = 8641206

Showing the first eight; more decompositions exist.
