Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572940, here are decompositions:

7 + 33572933 = 33572940
13 + 33572927 = 33572940
19 + 33572921 = 33572940
29 + 33572911 = 33572940
43 + 33572897 = 33572940
59 + 33572881 = 33572940
83 + 33572857 = 33572940
113 + 33572827 = 33572940

Showing the first eight; more decompositions exist.
