Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503220, here are decompositions:

19 + 33503201 = 33503220
41 + 33503179 = 33503220
43 + 33503177 = 33503220
59 + 33503161 = 33503220
131 + 33503089 = 33503220
137 + 33503083 = 33503220
139 + 33503081 = 33503220
151 + 33503069 = 33503220

Showing the first eight; more decompositions exist.
