Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666452, here are decompositions:

59 + 8666393 = 8666452
71 + 8666381 = 8666452
83 + 8666369 = 8666452
101 + 8666351 = 8666452
233 + 8666219 = 8666452
251 + 8666201 = 8666452
269 + 8666183 = 8666452
293 + 8666159 = 8666452

Showing the first eight; more decompositions exist.
