Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175572, here are decompositions:

29 + 175543 = 175572
53 + 175519 = 175572
73 + 175499 = 175572
79 + 175493 = 175572
109 + 175463 = 175572
139 + 175433 = 175572
179 + 175393 = 175572
181 + 175391 = 175572

Showing the first eight; more decompositions exist.
