Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572866, here are decompositions:

3 + 33572863 = 33572866
17 + 33572849 = 33572866
53 + 33572813 = 33572866
167 + 33572699 = 33572866
179 + 33572687 = 33572866
419 + 33572447 = 33572866
449 + 33572417 = 33572866
557 + 33572309 = 33572866

Showing the first eight; more decompositions exist.
