Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4540, here are decompositions:

17 + 4523 = 4540
23 + 4517 = 4540
47 + 4493 = 4540
59 + 4481 = 4540
83 + 4457 = 4540
89 + 4451 = 4540
131 + 4409 = 4540
149 + 4391 = 4540

Showing the first eight; more decompositions exist.
