Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745522, here are decompositions:

29 + 8745493 = 8745522
73 + 8745449 = 8745522
103 + 8745419 = 8745522
179 + 8745343 = 8745522
193 + 8745329 = 8745522
211 + 8745311 = 8745522
223 + 8745299 = 8745522
281 + 8745241 = 8745522

Showing the first eight; more decompositions exist.
