Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537180, here are decompositions:

7 + 33537173 = 33537180
13 + 33537167 = 33537180
37 + 33537143 = 33537180
59 + 33537121 = 33537180
67 + 33537113 = 33537180
181 + 33536999 = 33537180
197 + 33536983 = 33537180
239 + 33536941 = 33537180

Showing the first eight; more decompositions exist.
