Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5442, here are decompositions:

5 + 5437 = 5442
11 + 5431 = 5442
23 + 5419 = 5442
29 + 5413 = 5442
43 + 5399 = 5442
61 + 5381 = 5442
109 + 5333 = 5442
139 + 5303 = 5442

Showing the first eight; more decompositions exist.
