Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573820, here are decompositions:

11 + 33573809 = 33573820
23 + 33573797 = 33573820
167 + 33573653 = 33573820
239 + 33573581 = 33573820
257 + 33573563 = 33573820
347 + 33573473 = 33573820
389 + 33573431 = 33573820
419 + 33573401 = 33573820

Showing the first eight; more decompositions exist.
