Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745552, here are decompositions:

5 + 8745547 = 8745552
29 + 8745523 = 8745552
59 + 8745493 = 8745552
103 + 8745449 = 8745552
199 + 8745353 = 8745552
223 + 8745329 = 8745552
241 + 8745311 = 8745552
311 + 8745241 = 8745552

Showing the first eight; more decompositions exist.
