Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4548, here are decompositions:

29 + 4519 = 4548
31 + 4517 = 4548
41 + 4507 = 4548
67 + 4481 = 4548
97 + 4451 = 4548
101 + 4447 = 4548
107 + 4441 = 4548
127 + 4421 = 4548

Showing the first eight; more decompositions exist.
