Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572642, here are decompositions:

13 + 33572629 = 33572642
109 + 33572533 = 33572642
139 + 33572503 = 33572642
331 + 33572311 = 33572642
601 + 33572041 = 33572642
613 + 33572029 = 33572642
709 + 33571933 = 33572642
769 + 33571873 = 33572642

Showing the first eight; more decompositions exist.
