Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572778, here are decompositions:

37 + 33572741 = 33572778
79 + 33572699 = 33572778
131 + 33572647 = 33572778
149 + 33572629 = 33572778
241 + 33572537 = 33572778
251 + 33572527 = 33572778
257 + 33572521 = 33572778
331 + 33572447 = 33572778

Showing the first eight; more decompositions exist.
