Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538420, here are decompositions:

17 + 33538403 = 33538420
53 + 33538367 = 33538420
107 + 33538313 = 33538420
173 + 33538247 = 33538420
197 + 33538223 = 33538420
317 + 33538103 = 33538420
449 + 33537971 = 33538420
479 + 33537941 = 33538420

Showing the first eight; more decompositions exist.
