Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538000, here are decompositions:

29 + 33537971 = 33538000
59 + 33537941 = 33538000
101 + 33537899 = 33538000
137 + 33537863 = 33538000
191 + 33537809 = 33538000
233 + 33537767 = 33538000
311 + 33537689 = 33538000
317 + 33537683 = 33538000

Showing the first eight; more decompositions exist.
