Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585920, here are decompositions:

13 + 33585907 = 33585920
61 + 33585859 = 33585920
139 + 33585781 = 33585920
283 + 33585637 = 33585920
307 + 33585613 = 33585920
337 + 33585583 = 33585920
367 + 33585553 = 33585920
541 + 33585379 = 33585920

Showing the first eight; more decompositions exist.
