Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479440, here are decompositions:

23 + 33479417 = 33479440
41 + 33479399 = 33479440
89 + 33479351 = 33479440
179 + 33479261 = 33479440
233 + 33479207 = 33479440
461 + 33478979 = 33479440
563 + 33478877 = 33479440
719 + 33478721 = 33479440

Showing the first eight; more decompositions exist.
