Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509844, here are decompositions:

23 + 33509821 = 33509844
31 + 33509813 = 33509844
41 + 33509803 = 33509844
61 + 33509783 = 33509844
101 + 33509743 = 33509844
103 + 33509741 = 33509844
131 + 33509713 = 33509844
163 + 33509681 = 33509844

Showing the first eight; more decompositions exist.
