Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572648, here are decompositions:

19 + 33572629 = 33572648
127 + 33572521 = 33572648
271 + 33572377 = 33572648
337 + 33572311 = 33572648
397 + 33572251 = 33572648
457 + 33572191 = 33572648
607 + 33572041 = 33572648
619 + 33572029 = 33572648

Showing the first eight; more decompositions exist.
