Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5556, here are decompositions:

29 + 5527 = 5556
37 + 5519 = 5556
53 + 5503 = 5556
73 + 5483 = 5556
79 + 5477 = 5556
107 + 5449 = 5556
113 + 5443 = 5556
137 + 5419 = 5556

Showing the first eight; more decompositions exist.
