Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28572, here are decompositions:

13 + 28559 = 28572
23 + 28549 = 28572
31 + 28541 = 28572
59 + 28513 = 28572
73 + 28499 = 28572
79 + 28493 = 28572
109 + 28463 = 28572
139 + 28433 = 28572

Showing the first eight; more decompositions exist.
