Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512142, here are decompositions:

5 + 33512137 = 33512142
29 + 33512113 = 33512142
31 + 33512111 = 33512142
43 + 33512099 = 33512142
73 + 33512069 = 33512142
89 + 33512053 = 33512142
109 + 33512033 = 33512142
163 + 33511979 = 33512142

Showing the first eight; more decompositions exist.
