Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644206, here are decompositions:

19 + 8644187 = 8644206
59 + 8644147 = 8644206
83 + 8644123 = 8644206
149 + 8644057 = 8644206
157 + 8644049 = 8644206
283 + 8643923 = 8644206
313 + 8643893 = 8644206
317 + 8643889 = 8644206

Showing the first eight; more decompositions exist.
