Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557390, here are decompositions:

3 + 33557387 = 33557390
67 + 33557323 = 33557390
73 + 33557317 = 33557390
193 + 33557197 = 33557390
271 + 33557119 = 33557390
313 + 33557077 = 33557390
379 + 33557011 = 33557390
397 + 33556993 = 33557390

Showing the first eight; more decompositions exist.
