Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572986, here are decompositions:

3 + 33572983 = 33572986
53 + 33572933 = 33572986
59 + 33572927 = 33572986
89 + 33572897 = 33572986
137 + 33572849 = 33572986
173 + 33572813 = 33572986
449 + 33572537 = 33572986
569 + 33572417 = 33572986

Showing the first eight; more decompositions exist.
