Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4518, here are decompositions:

5 + 4513 = 4518
11 + 4507 = 4518
37 + 4481 = 4518
61 + 4457 = 4518
67 + 4451 = 4518
71 + 4447 = 4518
97 + 4421 = 4518
109 + 4409 = 4518

Showing the first eight; more decompositions exist.
