Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623180, here are decompositions:

7 + 33623173 = 33623180
13 + 33623167 = 33623180
43 + 33623137 = 33623180
79 + 33623101 = 33623180
103 + 33623077 = 33623180
109 + 33623071 = 33623180
271 + 33622909 = 33623180
307 + 33622873 = 33623180

Showing the first eight; more decompositions exist.
