Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537018, here are decompositions:

19 + 33536999 = 33537018
79 + 33536939 = 33537018
131 + 33536887 = 33537018
139 + 33536879 = 33537018
167 + 33536851 = 33537018
199 + 33536819 = 33537018
211 + 33536807 = 33537018
311 + 33536707 = 33537018

Showing the first eight; more decompositions exist.
