Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579440, here are decompositions:

31 + 33579409 = 33579440
43 + 33579397 = 33579440
73 + 33579367 = 33579440
109 + 33579331 = 33579440
157 + 33579283 = 33579440
163 + 33579277 = 33579440
229 + 33579211 = 33579440
373 + 33579067 = 33579440

Showing the first eight; more decompositions exist.
