Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509142, here are decompositions:

13 + 33509129 = 33509142
71 + 33509071 = 33509142
101 + 33509041 = 33509142
103 + 33509039 = 33509142
113 + 33509029 = 33509142
131 + 33509011 = 33509142
223 + 33508919 = 33509142
239 + 33508903 = 33509142

Showing the first eight; more decompositions exist.
