Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479240, here are decompositions:

31 + 33479209 = 33479240
73 + 33479167 = 33479240
79 + 33479161 = 33479240
229 + 33479011 = 33479240
241 + 33478999 = 33479240
283 + 33478957 = 33479240
313 + 33478927 = 33479240
337 + 33478903 = 33479240

Showing the first eight; more decompositions exist.
