Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745564, here are decompositions:

7 + 8745557 = 8745564
11 + 8745553 = 8745564
13 + 8745551 = 8745564
17 + 8745547 = 8745564
41 + 8745523 = 8745564
71 + 8745493 = 8745564
127 + 8745437 = 8745564
197 + 8745367 = 8745564

Showing the first eight; more decompositions exist.
