Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666232, here are decompositions:

13 + 8666219 = 8666232
31 + 8666201 = 8666232
59 + 8666173 = 8666232
73 + 8666159 = 8666232
79 + 8666153 = 8666232
139 + 8666093 = 8666232
163 + 8666069 = 8666232
173 + 8666059 = 8666232

Showing the first eight; more decompositions exist.
