Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4500, here are decompositions:

7 + 4493 = 4500
17 + 4483 = 4500
19 + 4481 = 4500
37 + 4463 = 4500
43 + 4457 = 4500
53 + 4447 = 4500
59 + 4441 = 4500
79 + 4421 = 4500

Showing the first eight; more decompositions exist.
