Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538042, here are decompositions:

29 + 33538013 = 33538042
71 + 33537971 = 33538042
101 + 33537941 = 33538042
179 + 33537863 = 33538042
233 + 33537809 = 33538042
353 + 33537689 = 33538042
359 + 33537683 = 33538042
443 + 33537599 = 33538042

Showing the first eight; more decompositions exist.
