Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518916, here are decompositions:

7 + 33518909 = 33518916
23 + 33518893 = 33518916
43 + 33518873 = 33518916
83 + 33518833 = 33518916
97 + 33518819 = 33518916
103 + 33518813 = 33518916
149 + 33518767 = 33518916
239 + 33518677 = 33518916

Showing the first eight; more decompositions exist.
