Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5438, here are decompositions:

7 + 5431 = 5438
19 + 5419 = 5438
31 + 5407 = 5438
157 + 5281 = 5438
211 + 5227 = 5438
229 + 5209 = 5438
241 + 5197 = 5438
271 + 5167 = 5438

Showing the first eight; more decompositions exist.
