Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557042, here are decompositions:

31 + 33557011 = 33557042
73 + 33556969 = 33557042
139 + 33556903 = 33557042
163 + 33556879 = 33557042
331 + 33556711 = 33557042
613 + 33556429 = 33557042
619 + 33556423 = 33557042
643 + 33556399 = 33557042

Showing the first eight; more decompositions exist.
