Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745212, here are decompositions:

13 + 8745199 = 8745212
43 + 8745169 = 8745212
79 + 8745133 = 8745212
181 + 8745031 = 8745212
193 + 8745019 = 8745212
271 + 8744941 = 8745212
283 + 8744929 = 8745212
379 + 8744833 = 8745212

Showing the first eight; more decompositions exist.
