Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479390, here are decompositions:

13 + 33479377 = 33479390
19 + 33479371 = 33479390
37 + 33479353 = 33479390
67 + 33479323 = 33479390
73 + 33479317 = 33479390
181 + 33479209 = 33479390
223 + 33479167 = 33479390
229 + 33479161 = 33479390

Showing the first eight; more decompositions exist.
