Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558400, here are decompositions:

59 + 33558341 = 33558400
107 + 33558293 = 33558400
131 + 33558269 = 33558400
137 + 33558263 = 33558400
263 + 33558137 = 33558400
347 + 33558053 = 33558400
401 + 33557999 = 33558400
419 + 33557981 = 33558400

Showing the first eight; more decompositions exist.
