Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666846, here are decompositions:

7 + 8666839 = 8666846
37 + 8666809 = 8666846
73 + 8666773 = 8666846
79 + 8666767 = 8666846
163 + 8666683 = 8666846
313 + 8666533 = 8666846
367 + 8666479 = 8666846
499 + 8666347 = 8666846

Showing the first eight; more decompositions exist.
