Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745500, here are decompositions:

7 + 8745493 = 8745500
157 + 8745343 = 8745500
193 + 8745307 = 8745500
277 + 8745223 = 8745500
331 + 8745169 = 8745500
367 + 8745133 = 8745500
433 + 8745067 = 8745500
571 + 8744929 = 8745500

Showing the first eight; more decompositions exist.
