Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4512, here are decompositions:

5 + 4507 = 4512
19 + 4493 = 4512
29 + 4483 = 4512
31 + 4481 = 4512
61 + 4451 = 4512
71 + 4441 = 4512
89 + 4423 = 4512
103 + 4409 = 4512

Showing the first eight; more decompositions exist.
