Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738428, here are decompositions:

29 + 8738399 = 8738428
89 + 8738339 = 8738428
197 + 8738231 = 8738428
227 + 8738201 = 8738428
449 + 8737979 = 8738428
557 + 8737871 = 8738428
599 + 8737829 = 8738428
719 + 8737709 = 8738428

Showing the first eight; more decompositions exist.
