Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509180, here are decompositions:

7 + 33509173 = 33509180
31 + 33509149 = 33509180
37 + 33509143 = 33509180
109 + 33509071 = 33509180
139 + 33509041 = 33509180
151 + 33509029 = 33509180
163 + 33509017 = 33509180
193 + 33508987 = 33509180

Showing the first eight; more decompositions exist.
