Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585728, here are decompositions:

109 + 33585619 = 33585728
349 + 33585379 = 33585728
439 + 33585289 = 33585728
487 + 33585241 = 33585728
499 + 33585229 = 33585728
541 + 33585187 = 33585728
601 + 33585127 = 33585728
727 + 33585001 = 33585728

Showing the first eight; more decompositions exist.
