Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33480018, here are decompositions:

17 + 33480001 = 33480018
29 + 33479989 = 33480018
109 + 33479909 = 33480018
139 + 33479879 = 33480018
149 + 33479869 = 33480018
157 + 33479861 = 33480018
199 + 33479819 = 33480018
211 + 33479807 = 33480018

Showing the first eight; more decompositions exist.
