Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752428, here are decompositions:

7 + 8752421 = 8752428
11 + 8752417 = 8752428
67 + 8752361 = 8752428
89 + 8752339 = 8752428
101 + 8752327 = 8752428
107 + 8752321 = 8752428
137 + 8752291 = 8752428
197 + 8752231 = 8752428

Showing the first eight; more decompositions exist.
