Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5428, here are decompositions:

11 + 5417 = 5428
29 + 5399 = 5428
41 + 5387 = 5428
47 + 5381 = 5428
131 + 5297 = 5428
149 + 5279 = 5428
167 + 5261 = 5428
191 + 5237 = 5428

Showing the first eight; more decompositions exist.
