Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4558, here are decompositions:

11 + 4547 = 4558
41 + 4517 = 4558
101 + 4457 = 4558
107 + 4451 = 4558
137 + 4421 = 4558
149 + 4409 = 4558
167 + 4391 = 4558
269 + 4289 = 4558

Showing the first eight; more decompositions exist.
