Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4428, here are decompositions:

5 + 4423 = 4428
7 + 4421 = 4428
19 + 4409 = 4428
31 + 4397 = 4428
37 + 4391 = 4428
71 + 4357 = 4428
79 + 4349 = 4428
89 + 4339 = 4428

Showing the first eight; more decompositions exist.
