Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752228, here are decompositions:

41 + 8752187 = 8752228
47 + 8752181 = 8752228
71 + 8752157 = 8752228
197 + 8752031 = 8752228
389 + 8751839 = 8752228
461 + 8751767 = 8752228
479 + 8751749 = 8752228
557 + 8751671 = 8752228

Showing the first eight; more decompositions exist.
