Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557240, here are decompositions:

37 + 33557203 = 33557240
43 + 33557197 = 33557240
97 + 33557143 = 33557240
109 + 33557131 = 33557240
139 + 33557101 = 33557240
163 + 33557077 = 33557240
193 + 33557047 = 33557240
229 + 33557011 = 33557240

Showing the first eight; more decompositions exist.
