Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4554, here are decompositions:

5 + 4549 = 4554
7 + 4547 = 4554
31 + 4523 = 4554
37 + 4517 = 4554
41 + 4513 = 4554
47 + 4507 = 4554
61 + 4493 = 4554
71 + 4483 = 4554

Showing the first eight; more decompositions exist.
