Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557130, here are decompositions:

11 + 33557119 = 33557130
29 + 33557101 = 33557130
43 + 33557087 = 33557130
53 + 33557077 = 33557130
67 + 33557063 = 33557130
73 + 33557057 = 33557130
83 + 33557047 = 33557130
137 + 33556993 = 33557130

Showing the first eight; more decompositions exist.
