Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4572, here are decompositions:

5 + 4567 = 4572
11 + 4561 = 4572
23 + 4549 = 4572
53 + 4519 = 4572
59 + 4513 = 4572
79 + 4493 = 4572
89 + 4483 = 4572
109 + 4463 = 4572

Showing the first eight; more decompositions exist.
