Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5436, here are decompositions:

5 + 5431 = 5436
17 + 5419 = 5436
19 + 5417 = 5436
23 + 5413 = 5436
29 + 5407 = 5436
37 + 5399 = 5436
43 + 5393 = 5436
89 + 5347 = 5436

Showing the first eight; more decompositions exist.
