Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666852, here are decompositions:

3 + 8666849 = 8666852
13 + 8666839 = 8666852
43 + 8666809 = 8666852
79 + 8666773 = 8666852
373 + 8666479 = 8666852
409 + 8666443 = 8666852
421 + 8666431 = 8666852
433 + 8666419 = 8666852

Showing the first eight; more decompositions exist.
