Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4438, here are decompositions:

17 + 4421 = 4438
29 + 4409 = 4438
41 + 4397 = 4438
47 + 4391 = 4438
89 + 4349 = 4438
101 + 4337 = 4438
149 + 4289 = 4438
167 + 4271 = 4438

Showing the first eight; more decompositions exist.
