Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479238, here are decompositions:

7 + 33479231 = 33479238
29 + 33479209 = 33479238
31 + 33479207 = 33479238
71 + 33479167 = 33479238
97 + 33479141 = 33479238
131 + 33479107 = 33479238
227 + 33479011 = 33479238
239 + 33478999 = 33479238

Showing the first eight; more decompositions exist.
