Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17556, here are decompositions:

5 + 17551 = 17556
17 + 17539 = 17556
37 + 17519 = 17556
47 + 17509 = 17556
59 + 17497 = 17556
67 + 17489 = 17556
73 + 17483 = 17556
79 + 17477 = 17556

Showing the first eight; more decompositions exist.
