Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5538, here are decompositions:

7 + 5531 = 5538
11 + 5527 = 5538
17 + 5521 = 5538
19 + 5519 = 5538
31 + 5507 = 5538
37 + 5501 = 5538
59 + 5479 = 5538
61 + 5477 = 5538

Showing the first eight; more decompositions exist.
