Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572920, here are decompositions:

23 + 33572897 = 33572920
71 + 33572849 = 33572920
107 + 33572813 = 33572920
179 + 33572741 = 33572920
233 + 33572687 = 33572920
383 + 33572537 = 33572920
431 + 33572489 = 33572920
503 + 33572417 = 33572920

Showing the first eight; more decompositions exist.
