Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4458, here are decompositions:

7 + 4451 = 4458
11 + 4447 = 4458
17 + 4441 = 4458
37 + 4421 = 4458
61 + 4397 = 4458
67 + 4391 = 4458
101 + 4357 = 4458
109 + 4349 = 4458

Showing the first eight; more decompositions exist.
