Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572786, here are decompositions:

7 + 33572779 = 33572786
43 + 33572743 = 33572786
73 + 33572713 = 33572786
103 + 33572683 = 33572786
139 + 33572647 = 33572786
157 + 33572629 = 33572786
229 + 33572557 = 33572786
283 + 33572503 = 33572786

Showing the first eight; more decompositions exist.
