Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745492, here are decompositions:

43 + 8745449 = 8745492
73 + 8745419 = 8745492
139 + 8745353 = 8745492
149 + 8745343 = 8745492
163 + 8745329 = 8745492
181 + 8745311 = 8745492
193 + 8745299 = 8745492
251 + 8745241 = 8745492

Showing the first eight; more decompositions exist.
