Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572980, here are decompositions:

47 + 33572933 = 33572980
53 + 33572927 = 33572980
59 + 33572921 = 33572980
83 + 33572897 = 33572980
131 + 33572849 = 33572980
167 + 33572813 = 33572980
239 + 33572741 = 33572980
281 + 33572699 = 33572980

Showing the first eight; more decompositions exist.
