Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572808, here are decompositions:

29 + 33572779 = 33572808
67 + 33572741 = 33572808
107 + 33572701 = 33572808
109 + 33572699 = 33572808
179 + 33572629 = 33572808
251 + 33572557 = 33572808
271 + 33572537 = 33572808
281 + 33572527 = 33572808

Showing the first eight; more decompositions exist.
