Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507144, here are decompositions:

7 + 33507137 = 33507144
23 + 33507121 = 33507144
37 + 33507107 = 33507144
107 + 33507037 = 33507144
197 + 33506947 = 33507144
241 + 33506903 = 33507144
347 + 33506797 = 33507144
367 + 33506777 = 33507144

Showing the first eight; more decompositions exist.
