Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520144, here are decompositions:

17 + 33520127 = 33520144
41 + 33520103 = 33520144
83 + 33520061 = 33520144
101 + 33520043 = 33520144
113 + 33520031 = 33520144
131 + 33520013 = 33520144
353 + 33519791 = 33520144
521 + 33519623 = 33520144

Showing the first eight; more decompositions exist.
