Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512988, here are decompositions:

11 + 33512977 = 33512988
29 + 33512959 = 33512988
59 + 33512929 = 33512988
107 + 33512881 = 33512988
149 + 33512839 = 33512988
151 + 33512837 = 33512988
181 + 33512807 = 33512988
241 + 33512747 = 33512988

Showing the first eight; more decompositions exist.
